Plenary Talk: US NAE Member Prof. Mark Lundstrom, Electrical & Computer Engineering, Purdue University

In 1960, Frederick Emmons Terman gave a remarkable speech at the 16th National Electronics Conference in Chicago. Vacuum tubes reigned supreme, but he saw a “new electronics”:
“This new electronics lives close to the frontiers of science, and requires a high level of technical competence. It grows by the development of new products. It is characterized by the transistor and other solid-state devices.”
This was one year after the invention of the intregrated circuit and well before universities taught solid-state electronics, but Terman saw the future. Moore’s Law subsequently transformed the world, but we now see the end of device scaling. Electronics will continue to advance and the impact on society will grow, but things are changing. Increasingly, progress will be driven by technology integration, system design, and software. Will 21st Century electronics be about realizing the potential of Terman’s new electronics, or is there a new, new electronics?
In this talk, I will reflect on the successes of the past, identify some key lessons from those successes, and argue that we now have an opportunity to create a new, new electronics. This new electronics will be much broader – touching a much wider range societal challenges and enabled by a much wider range of science. It will be done by teams that transcend disciplines. It will be driven by problems, and it will re-shape disciplines, create new ones, and identify fundamental research questions. Education will play a critical role – just as it did during the microelectronics revolution. Problem-driven research will energize a new generation of engineer-scientists and provide them with the experiences and education they need to become technology leaders for the 21st Century. There is no roadmap to this new electronics, but the opportunity is there. My goal in this talk is to challenge us as a community to energize electronics technology research and development for a new century."

Nitride semiconductors are attractive materials not only for efficient LED/LD lighting but also clean energy generator. Nitride photocatalyst what I invented is able to split water into H2 and O2 gases by using light energy without external bias. This catalyst also can reduce CO2 molecules become hydrocarbons such as HCOOH, CH4, C2H5OH. These phenomena can realize clean energy generation by using natural energy such as solar light. Key technologies are metalorganic vapor-phase epitaxy (MOVPE) growth of high-quality InGaN and invention of NiO co-catalyst on nitride photocatalyst.
Based on numerical analysis about chemical states of MOVPE, we have succeeded to raise growth temperatures of InGaN by 100°C. Higher temperature realizes growth of higher-quality InGaN, resulting InGaN LEDs from violet to deep red (the MOVPE world record). Efficient light emitting is related to efficient light absorption such as photocatalyst.
In photocatalyst, the upper most InGaN layer absorbs light, and electron-hole pairs are created in its bandgap. Electrons go inside of InGaN and reduce water or CO2, then H2 gas or hydrocarbons are evolved, respectively. Problem is oxidation by holes. If holes go out from nitride surface, O2 gas will be obtained from the surface. Holes, however, oxidize semiconductor itself. This becomes photo-corrosion. Co-catalyst materials what we found out are able to stop photo-corrosion and enhance water oxidation. Energy conversion efficiency is already more than average of biological photosynthetic one.

KSA Industry Talk: Dr. Ghaitan A. Al-Muntasheri, Chief Technologist, EXPEC Advanced Research Center, Saudi ARAMCO

Oil and gas will continue to be the backbone of the global energy supply, and natural gas will become even more important in decades to come. The industry’s challenge is to employ the right technologies, ensuring reliable production and sustainable supply. Saudi Aramco Upstream R&D is focused to achieve key objectives; ranging from expanding the kingdom’s hydrocarbon resources and increasing recovery. Therefore, Saudi Aramco’s EXPEC Advanced Research Center has been steered to create innovative and high impact solutions in wide domains including Drilling, Production, Reservoir, Geology, Geophysics and Computational modelling. However, when it comes to downhole monitoring applications, oil and gas industry is dealing with extremely harsh environments. The current fields are structurally complex and require multi-configuration development stages. Therefore, the need for timely, accurate, reliable information about how our reservoirs are performing is an important component in optimizing the production of our oil and gas fields. For this, we need advanced technologies with new capabilities for sensing a wide range of parameters, such as pressure, temperature, vibration, and flow regimes.  In production applications, EXPEC ARC is developing advanced sensors to be able to economically complete, control, monitor, and sustain well production. As an example, we are developing Distributed Temperature Sensing (DTS) fiber-optic technology that can provide permanent monitoring and measure temperature over long intervals extending up to the complete length of the wellbore. In Geophysics, scientists successfully installed permanent buried sensors to monitor CO2 injection and capture the rapid fluid movement. Additionally, a multispectral sensing technology, which will help in determining the key shale reservoir properties in the field, is being developed. For Saudi Aramco to accomplish its R&D mission, we seek to engender the local research and technology ecosystem. As an example, Saudi Aramco is collaborating with KAUST centers to develop a non-radioactive microwave based water cut meter and a new type of laser box, a broadband laser, for our upstream fiber optic work. We are also undertaking major international collaboration. With our subsidiaries, we are creating a robust network of global research centers in Europe, North America and Asia.

Bright Mind Talk: Dr. Sophie Meuret, AMOLF, Netherlands

We introduce time-resolved cathodoluminescence (CL) imaging spectroscopy using a 30 keV scanning electron microscope equipped with an ultrafast electrostatic beam blanker, in combination with a cathodoluminescence analysis system. Electron pulse trains with arbitrary time profiles are achieved with a time resolution of 5 ns. We use time-correlated single-photon detection to measure the CL autocorrelation function g2(τ) for InGaN/GaN quantum wells using Hanbury-Brown-Twiss interferometry. We find strong CL photon bunching (g(2)(0)>10) indicating that a single electron creates multiple excitonic quantum well excitations. Further increased bunching is observed under a pulsed excitation. A Monte Carlo model taking into account interacting secondary electron cascades, carrier diffusion and the interplay between excitation and spontaneous emission describe the data well.

Networked systems of tiny wireless and sensing-enabled devices continue to give birth to a host of new applications that range from medical sensors for image-guided surgery, to distributed image-based surveillance of remote areas for security or environmental reasons. Such applications mandate new requirements in terms of size of the devices as well as the bandwidth required. Extreme requirements for small size packaging of the devices are obvious for many applications including biomedical ones. Fully integrated sensor modules that are capable of harvesting energy, sensing the environment and communicating with other sensors or base stations are becoming a necessity. Despite the development chips for these systems, there continues to be a need for improved implementations of micro-scale detection and processing systems for further convenience, scaling and portability. These systems would include a sensor module (mostly in mems), attached to analog front end circuitry, an analog to digital converter and a wireless communication module. We will present the research conducted at KAUST addressing many of these components.

KAUST Faculty Talk: Associate Prof. Jr. Hau He, EE

Great advances have been made in developing cheap, simple, multi-functional and energy-saving fabrication processes for flexible electronics. Paper, as a flexible, foldable, cost-efficient and mass productive substrate, has shown diverse applications for flexible electronics to meet such demand. Recently, we have successfully demonstrated the first nonvolatile resistive memory using paper as substrates by means of all-printing techniques. Moreover, we also implemented the algorithm of Origami art into the device design for the flexible electronics, such as photodetectors and nanogenerators, taking advantage of the foldability and adaptability of paper substrates. In particular, paper origami triboelectric nanogenerators using paper as the starting material, with high degree of flexibility, light weight, low cost, and recyclability is presented. We believe that these findings will pave a way for future energy harvesting and sensor design, especially for the development of green flexible electronics.

The III-nitride wide bandgap material has tremendous potential for UV optoelectronics for water sterilization, communication, and biochemical sensing. I will present the latest research progress related to the development of this material.

2:30 PM

Keynote Talk: Assoc. Prof. Jiaxing Huang, Material Science and Engineering, Northwestern University

In this talk, I will discuss a few curiosity-driven discoveries inspired by non-scientific sources that lead to new hypotheses and solutions for solving material problems. For example, crumpled paper balls in a waste basket inspired a new form of ultrafine particles that becomes aggregation-resistant and can disperse in arbitrary solvents. This represents a new way to achieve colloidal processability without the need for surface chemistry. In another example, nanopatterns in Blu-ray movie discs are found to be useful for improving the performance of solar cells through light trapping, which inspires a new way to design nanopatterns with the help of information processing algorithms. Finally, I will share a few examples of how curiosity-driven enquiry enhances student learning experience. In one example, a question asked by students after class inspired their creation of sensors from office and toy pencils.

KAUST Faculty Talk: Assoc. Prof. Jurgen Kosel, EE

Magnetic transducers have played a central role in the areas of sensors and actuators since the discovery of the compass more than 2000 years ago. With the advent of new fabrication methods, magnetic transducers have been developed at the micro and nano scale, exploiting novel properties and providing new features.
Cylindrical magnetic nanowires are new materials that offer unique properties mainly due to a high aspect ratio and shape anisotropy. They are characterized by a single magnetic domain, rendering them permanent magnetic. This feature allows utilizing such nanowires as remotely operated nanorobots, i.e. induce motion, produce heat or sense their location.
In this talk, I will present novel magnetic nanowire transducers, for which we developed a facile and efficient fabrication method. The nanowires are highly biocompatible and temperature resistant. The applications range from magnetic nanocomposites, artificial skins, corrosion sensing, energy harvesting, drug delivery to cancer treatment. The magnetic nanowire-based transducers enable both new functionalities as well as a power reduction up to several orders of magnitude compared to similar methods.

3:50 PM

KAUST Faculty Talk: Assoc. Prof. Aurelien Manchon, MSE

Chiral objects are ubiquitous in science and pose fundamental challenges, such as the importance of chiral molecules in commercial drugs or the dominance of matter over antimatter in the universe. Magnetic materials lacking inversion symmetry, called chiral magnets, constitute a unique platform for the exploration and control of chiral objects. In these systems, typically transition metal multilayers, interfacial spin-orbit coupling adopts a peculiar form under inversion symmetry breaking. This enables a wealth of physical phenomena, among which the emergence of magnetic skyrmions – topological magnetic textures –, and spin-orbit torques – an efficient means to electrically control magnetization dynamics.
I will present various aspects of the interplay between spin transport and magnetization dynamics mediated by spin-orbit coupling in chiral magnets. I will first examine how interfacial spin-orbit coupling facilitates the onset of chiral magnetic textures. I will then review the non-equilibrium properties of such multilayers, focusing on the electrical generation of magnetic torques, called spin-orbit torques, which enable the efficient manipulation of magnetic textures. Finally, I will show that topological spin transport in these magnetic textures produces enhanced torque efficiency as well as chiral damping, i.e. energy dissipation depending on the chirality of the texture.

KAUST Alumni Talk: Ahmed Alfadhel, PhD, EE, 2016 Postdoc, Rochester Institute of Technology, New York

Microfluidics-based electronics have shown great potential in numerous applications, such as energy harvesters, bio-inspired devices, and wearable healthcare sensors. Fabrication challenges and material incompatibilities pose barriers to achieving the full potential of this emerging field. Elastomeric flexible microfluidic channels are conventionally fabricated by casting on a micro-machined mold, followed by a bonding step. Difficulty fabricating multilayers, and weak bonding to many substrates limit device capabilities and scalability. Integration of transducers within microfluidic channels is also challenging, especially for materials requiring high temperature annealing.
Novel processing techniques for the realization of scalable and flexible microfluidic electronics have been developed to suit a wide range of substrates. Biocompatible Polyethylene-glycol (PEG) is Inkjet-printed as a sacrificial layer. Elastomers, the channels’ structural material, are cast on PEG and cured. PEG can then be removed through heating above its phase-change temperature. This process allows easy modulation of the shape and dimensions of the channels on any substrate, and eliminates the need of manual realization of multilayers interconnection. Integration of ferroelectric and magnetic sensors is demonstrated with a photonic annealing process that enables film heating to over 900°C with insignificant substrate heating. Combined, these techniques enable realization of a new generation of wearable, flexible microfluidic electronics.

Three-dimensional lead halide perovskites exhibit impressive long carrier diffusion lengths and low trap densities, while so-called lower dimensional perovskites such as two-dimensional (i.e. layered), zero-dimensional, and perovskite quantum dots, possess large exciton binding energies  and high photoluminescence quantum yields.  These characteristics make the diverse class of perovskite materials ideal for photodetection, photovoltaics, and light emission. Here we discuss our latest advances in growing and understanding the properties of monocyrstalline perovskites and perovskite nanocrystals, as well as zero-dimensional and two-dimensional perovskites. We demonstrate the integration of these materials in a wide array of optoelectronic applications including: visible-blind UV-photodetectors, simultaneously fast and sensitive photodetectors that can operate in both broad-band and narrow-band regimes, monocrystalline perovskite solar cells, efficient light-emitting diodes, and color converters for gigabit-rate data transmission with visible light communication systems.  Thus, in these device prototypes, we demonstrate the importance of crystallinity, dimensionality, and composition for realizing novel, low-cost and efficient perovskite optoelectronics.

Plenary Talk: IEEE Life Fellow Prof. Franco Maloberti, President, IEEE CAS Society

Recent years witnessed an increasing demand for so-called autonomous applications, that means applications that do not need and do not have the possibility of refueling the energy as it is commonly done with battery operated devices.
This kind of systems harvests power from the environment by transforming what is available into electrical form. Moreover, they are not in the same spatial positions, but move around transported by persons or objects: they are nomadic electronic systems.
Communication is their key feature and the high computing requirements impose using the Web to obtain nodes if the so-called Internet of Things (IoT).

Since harvested power is very low good autonomy imposes using electronic consuming very low power. Moreover, transducers used to transform the energy into electrical form can generate a very low voltage.

Designing low power and low voltage electronics for IoT systems is the present challenge. Many applications require sub 1-V supply voltages and with power consumption in the hundreds of nW range while preserving good performances.

The analog-to-digital converters are essential for modern IoT system. Moreover, power management at ultra-low power level is crucial. Techniques and recent circuit implementations capable of satisfying diverse requests will be presented.

9:45 AM

KAUST Faculty Talk: Prof. Boon Ooi, EE Director, KACST-KAUST TIC on Solid State Lighting

Group-III nitride materials have been intensively studied because the alloys have direct bandgaps covering the whole visible spectrum, thus attractive for solid-state lighting, visible light communications, solar cells, solar water splitting, etc. However, these materials are typically grown on sapphire substrates, which results in high density of threading dislocations because of the thermal- and lattice-mismatch, thereby reducing the quantum efficiencies of III-nitride based devices. Moreover, the electron-hole wavefunctions separation with increasing indium composition leads to decreasing quantum efficiency for these devices grown on c-plane sapphire. Nanowire LEDs on silicon may circumvent these disadvantages faced by planar epitaxial LEDs, promising great advantages, such as low defect density, wavelength tunability, and improved light extraction. The blue, green, and red LEDs grown using molecular beam epitaxy (MBE) demonstrated the potential of nanowires emitters for practical applications, beyond lighting.  In this talk, we will present our research on III-N nanowires LEDs and edge-emitting lasers at UV-to-NIR wavelength range. We will also report the enhanced heat dissipation by growing nanowires-crystal on metal substrates. Applications of visible lasers to visible light communication, underwater communication and indoor horticulture will also be discussed.

Consumers demands for societal challenges in the fields of healthcare, mobile transportation, smart energy and Internet of Things are driving the revolution and innovation in micro- and nano- electronics. Things, homes and cities will become smart and interact with each other, posing challenges on the availability of dedicated sensors, detectors, monitors, diagnostic devices and the handling of big data. The global connectivity of persons, devices, systems and services is more than a hype. While the fixed internet connected one billion users via personal computers and the smartphones more than 5 billion people, the IoT is expected to connect more than 25 billion of “things” to the internet by 2020. To realize this millions of sensors and devices will be needed. While the market for connected vehicle technology only will already reach $54 billion by 2017, according to McKinsey Global Institute, the Internet of Things has the potential to create an economic impact of $2.7 trillion to $6.2 trillion annually by 2025.
By giving a variety of practical examples in different fields such as healthcare, agriculture, mobile transportation, etc it will be shown that the Internet of EveryThing is not a futuristic, aspirational technology trend, but something that is around the corner with a strong impact on the micro- and nano-electronics evolution in both More Moore and More Than Moore. This will create unknown opportunities for research, development and manufacturing companies.

10:45 AM

KSA Industry Talk: Dr. Alfonso Caraveo, Senior Scientist, SABIC at KAUST

Bright Mind Talk: Dr. Michele Conroy, Pacific Northwest National Laboratory, USA

Nanostructured semiconductors have a clear potential for improved optoelectronic devices, such as high-efficiency LEDs. However, most arrays of semiconductor nanorods suffer from having relatively low densities (or “fill factors”) and a high degree of nonuniformity, especially when produced by self-organized growth. Ideally an array of nanorods for an optoelectronic emitter should have a fill factor close to 100%, with uniform rod diameter and height. We present a “space-filling” approach for forming defect-free arrays of AlN nanorods, whereby the separation between each rod can be controlled to 5 nm due to a self-limiting process. These arrays of pyramidal-topped AlN nanorods formed over wafer-scale areas by MOCVD provide a defect-free semi-polar top surface, for potential optoelectronic device applications with the highest reported fill factor at 98%. We then applied this method to GaN, in particular investigating the desorption factor that was not an issue for the AlN growth. We show that the etched nanorods change morphology during the annealing step even before additional GaN is deposited, forming 6 non-polar side walls. Through controlled anneal steps pre growth and engineering a spaced out pre patterned substrate GaN nanorods can also be grown at the high fill factor seen in for AlN.

Presentation title: "No planet B, Earth in a State of Flux"

Amidst the constant overload of visual pollution we are exposed every day; how effective are art and design disciplines in communicating climate change and environmental issues? We know that art has the potential to move us. An image is worth a thousand words; a persuasive story compels us to buy a new product, to donate to a charity, to sign a petition or participate in a protest. Art can work so powerfully on our perceptions because artists tend to connect different spheres and orders of experience. Designers are very effective at connecting seemly unrelated things and help clients align around an idea to realize its full potential. Their approach to solving a wide range of problems is called “Design Thinking” and this framework has become a necessary component to turn abstract ideas into practical applications.

Designers work with users, clients, institutions, and communities to make things happen in the world. This presentation provides an overview of case studies of diverse design disciplines addressing climate change issues, where technological advances require a systems-thinking approach to developing sustainable products and services, while considering their social and environmental impacts for the long term. The design process starts with the here and now. Innovative ideas are generated from insights about our current reality, and how we envision alternative outcomes. The more we visualize the future we want, the more we are likely to do something to achieve it.

** State of Flux Poster Design Exhibition

A showcase of artwork created by undergraduate students in the Graphic Design program < http://fineartscomm.lamar.edu/art/academic-programs/graphic-design/> at Lamar University <http://www.lamar.edu> (in Texas, United States) under the guidance of Assistant Professor Natacha Poggio, as part of an Illustration assignment in which students were tasked to research and identify six issues of relevance from NASA's Image of Change website < http://climate.nasa.gov/state_of_flux>. The site features images of different locations on planet Earth, showing change over time periods ranging from centuries to days. Some of these effects are related to climate change, such as man-made interventions (e.g.; urbanization, deforestation, tar sands); some are natural hazards such as wildfires and floods. All images show our planet in a state of flux. Poggio’s students then illustrated these topics in a series of pictograms and posters raising awareness of the issues.

KAUST Faculty Talk: Associate Prof. Atif Shamim, EE

With the advent of Internet of Things (IoT), research in low cost wireless sensors has gained a lot of interest. The idea is that billions of sensors with wireless capabilities are placed on objects or dispersed in environment so that they can sense parameters of interest and communicate the data to other objects or servers so that smart decisions can be made in an automated fashion. Be it smart living in office or home environment or be it an early warning system for remote health care or large area environmental monitoring, the concept of IoT will revolutionize our life styles. In order to fulfill the requirements of billions of IoT sensors every year, a paradigm shift is required in manufacturing. That is where additive manufacturing comes into play as it has distinct advantages for low cost and large volume manufacturing of electronics. It is a completely digital process which does not require expensive masks or fabrication steps and excess material is not removed and wasted like typical subtractive methods. With inkjet, screen and gravure printing methods, roll-to-roll and real-to real processing are possible, enabling realization of millions of devices per minute. This talk introduces additive manufacturing (inkjet printing/3D Printing) as an emerging new technique to realize low cost and flexible wireless sensors suitable for IoT applications.

This talk will discuss work in our group to use liquid metals as conductors for stretchable, soft, and reconfigurable electronics.  We focus on alloys of gallium.  These alloys are noted for their low viscosity, low toxicity, and negligible volatility.  Despite the large surface tension of the metal, it can be molded into non-spherical 2D and 3D shapes due to the presence of an ultra-thin oxide skin that forms on its surface.  The metal can be patterned by injection into microchannels or by direct-write techniques including 3D printing.   Because it is a liquid, the metal is extremely soft and flows in response to stress to retain electrical continuity under extreme deformation. The ability of the oxide to reform instantaneously also allows the metal to self-heal in response to damage.  In addition, the ability to remove the oxide electrochemically provides a new means to control the shape of the metal for reconfigurable electronics.  Finally, we combine the metal with hydrogels to create electrodes, diodes, and memristor memory devices that are composed entirely out of soft, liquid-like materials.  These materials create comfortable interfaces with the skin for non-invasive sensing.

2:00 PM

Bright Mind Talk: Dr. Claire Chuang

High-quality Ge substrates have numerous applications, but the high cost of single-crystalline Ge makes the use of Ge-on-Si virtual substrates a more practical choice.  However, the high lattice mismatch between Ge and Si unavoidably leads to defects that degrade the Ge film when grown directly on top of Si.  An approach to mitigate these defects is selective epitaxial growth (SEG), in which an amorphous layer (e.g., SiO2) is employed as a mask between Ge and Si lattices to reduce the mismatch strain.  SEG has been demonstrated to produce high-quality Ge films on Si, although defects are not fully eliminated.  Further improvements will require quantitative understanding of the underlying atomic-scale mechanisms. 
In this presentation, an atomistic computational framework for the SEG system (Si/SiO2/Ge) is introduced. The model is validated using a variety of thermodynamic properties and is shown to provide a good overall description of the Si-Ge-O system. The framework is then applied to study Ge deposition on amorphous SiO2. It is shown that the simulations are able to access experimentally meaningful deposition conditions and reproduce several quantities related to the island size distribution. A new approach for accelerating deposition simulations is also discussed.

KAUST Faculty Talk: Assoc. Prof. Mohammad Younis, ME

Miniature structures and devices have captured the attention of the scientific community for several decades for their unprecedented attractive features. Today, several micro-electro-mechanical systems MEMS devices are being used in our everyday life, ranging from accelerometers and pressure sensors in automobiles, radio-frequency (RF) switches and microphones in cell phones, and inertia sensors in video games. Along with their great promise, micro and nano devices have brought new challenges and a wide spectrum of unexplained and less-understandable behaviors and phenomena. 
In this talk, we demonstrate that by developing a proper understanding and deep insight of the dynamics and nonlinear mechanics phenomena at the micro and nano sale, new technological solutions and innovative ideas can be realized leading to new generations of superior devices. The talk will first discuss the realization of smart switches triggered by the detection of a physical quantity. In one application, switches triggered by the detection of gas will be discussed. In another application, we demonstrate switches triggered by shock and acceleration, which can be used for the deployment of airbags in automobiles and for earthquake safety actions. The second part of the talk will discuss several interesting nonlinear behaviors of in-plane arches and their exploitation for logic, memory, filtering, and sensing applications.

Corrosion is a serious problem that can be found in all industries worldwide. In the United States alone, the cost of corrosion in industry was estimated in 2013 as greater than 1 trillion US dollar a year where it is estimated that in 2016 this will reach $1.1 trillion a year. Corrosion is particularly critical in the oil and gas industry, due to the vast amounts of metallic based assets located throughout the entire supply chain. Corrosion in metals reduces its mass, leading to performance and reliability reduction, causing leakages and equipment failure. It affects the assets of refineries, plants, the pipeline transportation network, it contaminate hydrocarbon products and cause serious impact on natural environments and human health. In Saudi Aramco, 61 % of damage mechanisms are directly related to corrosion. The cost of corrosion in 2003 according to the consultant service department in Saudi Aramco is estimated to be 900 million US dollar and in 2008 this cost increased to an estimated $1.75 billion per year! Therefore, there is a continuous effort in the research and development domain to find a solution to reduce corrosion impact and cost.

Detecting and monitoring corrosion in early stages is critical for oil and gas industries where it allows correct and timely decisions to be made, improving the lifetime of assets, selecting the correct materials, lowering the cost of corrosion and protect the natural recourses and human health. Nowadays, the majority of corrosion sensors are used offline that adds to the invisibility of corrosion, which is often observed when it is too late. In addition, the available corrosion-sensing technologies are developed using conventional solid electronics. Where the electronics is now entering an innovative phase of development aims to evolve from the traditional stiff, heavy and expensive electronics platform to a mechanically flexible, light and less expensive platform, known as flexible electronics. Transferring corrosion sensors to flexible electronic platform provides another dimension of applications and possibilities. For sustainable future, we are looking forward to develop a low coast flexible corrosion sensor for oil and gas applications with energy harvesting and wireless communications to provide, high coverage area of sensors to develop a network of corrosion sensors to be applied throughout oil and gas facilities. Embedded sensors can allow online measurements, to making the invisible visible.
