Speech Title: Energy Efficenet Wires: Ultraconductors and Covetics
Abstract: Energy-saving and increasing the efficiency of power transmission lines, electrical machines and transformers are important as much as diversity and renewability of energy resources. Considering the increasing power need it would be impossible to transmit dozens of GW power using the existing transmission lines due to the current carrying limitation of the metals used in transmission lines. Hence, it is a must to develop new materials for power transmission lines. The studies on energy-efficient materials, which can be alternative to superconductors and normal conductors, especially for applications of daily life are continued due to these disadvantages. It is known that new generation electrical materials on which the studies have been heavily performed in recent years have demonstrated close or better performances than superconductors in certain aspects even though they are not superconductors. One potential approach for decreasing metals electrical resistivity is the incorporation of carbon nanotubes into metal. In present work, we developed a unique method to obtain metal-CNT composite to get ultraconductive wire.
His current research interests include carbon nanostructures and composites, supercapacitors and energy storage systems employing 2D structures such as graphene, dichalcogenides and MXenes, biomedical and gas sensors, ultraconducting and superconducting cables, covetics, radar absorbers, metamaterials, superconducting and semiconducting devices.

Speech Title: Energy-Quality Scalability in Mobile Devices
Abstract: The main constraint of most mobile electronic devices is not computational power, but rather their energy consumption. These devices rely in fact on rich multi-core platforms with powerful accelerators that could be even exploited further, if it were not to the stringent constraints imposed by batteries. A paradigm that has recently emerged is the so-called "energy quality scalability", which leverages the fact that most functionalities of a mobile device are error-resilient: controlled errors in their operations do not have a dramatic impact on final quality of the outputs, but might allow to simplify the system and therefore save energy. This impact can be fully exploited in mobile systems, where most functionalities are meant for two human senses (sight and hearing) that have limited sensitivity. This talk will present some ideas that are particularly promising and also quite consolidated in the research community, but, in spite of their simplicity and economic sustainability, have not found their way into mobile devices.

Speech Title: Consumer Electronics Invades Healthcare
Abstract: There is a new generation of Consumer Electronics companies that have identified a market segment for consumers that want to stay healthy and fit. This market segment is growing rapidly for a number of reasons. Wearables are fashion items and serve a monitoring function. Wearables can track how active we are, and thus provide an incentive to keep “moving”. These fitness trackers are made for fun and to provide some feedback on how one is tracking with personal fitness goals. They are not intended to be used for healthcare applications. Newer wearables also include functions that track health performance indicators. They can measure blood pressure or blood glucose levels, or Oxygen levels to mention a few. These devices are not of medical grade, but many healthcare practitioners ask their patents to monitor their health using these devices. Their advantage is that they are low cost, reasonably accurate. Further innovation, the IoT, and low-cost mass-produced products are now invading the healthcare industry. Remote patient monitoring systems, fall detectors, driver alert systems, are new avenues where these consumer-grade devices are intruding in healthcare. This invasion is changing how healthcare practitioners are interacting with their patients. For one there is information overflow and privacy concerns. Will these devices be abused by thrill-seekers, who are starting to implant them to become Transhumans? Can medical device manufacturers’ justify the high cost of medical grade monitoring system when it can be done cheaper on a smartphone?

Speech Title: Autonomous self-powered and self-calibrated Microsystems for IoT applications
Abstract: “Autonomous Microsystems” refers to smart electronic systems that are able to sense, process and transmit useful information from the environment while being completely autonomous by harvesting readily available solar, thermal or kinetic ambient energy. Deployed in IoT applications, these smart devices are able to monitor water leakage in a water pipe, blood pressure in human body, temperature of frozen food items, but also humidity, air and water quality in intelligent buildings and smart cities. The design of “autonomous Microsystems” must take into consideration a number of challenging IoT constraints such as low cost, self-calibration to minimize human intervention, and self-power generation to replenish depleted energy resources. Silicon based technology is the only alternative solution offering single-chip solutions featuring the best trade-off in terms of cost/performance and enabling large scale integration and mass volume production leading to large scale deployment of “autonomous microsystem” devices in various emerging IoT applications with minimal human intervention.
This talk will present enabling technologies for IoT sensing addressing key issues related to power consumption, energy harvesting and calibration of “autonomous Microsystems”. Three case studies will be presented, namely: (i) smart vision systems with energy harvesting capabilities, (ii) Batteryless temperature sensing for passive RFID applications and (iii) olfactory sensors with self-calibration capability. The talk will cover state-of-the art technological developments in this area, and outline existing challenges as well as emerging new opportunities for research and innovation in this rapidly growing field. The conclusion of the talk will discuss whether “autonomous microsystems” are becoming a reality or is just another engineering dream idea.

Speech Title: Modeling, Simulation and Verification of Robotic Bicycle Dynamics and Control
Abstract: Recent progress in autonomous vehicles inspires renewed research in vehicle dynamics and control. Light and efficiently robotic electric bicycle has great potential to become the most energy efficient vehicles for urban transportation. It can serve as a perfect platform for shared single-track vehicle. In this abstract we apply symbolic math to obtain nonlinear analytic dynamics model for the vehicle. The holonomic and nonholonomic constraints from wheels are fully included. Based on the Euler-Lagrange equation, the nonlinear dynamics is shown to satisfy an underactuated manipulator equation. The symmetric mass matrix, Coriolis and centrifugal forces as well as gravitation contribution are all shown to be dependent on vehicle roll and steer angles. The complex dynamic model is then applied to simulate vehicle dynamics and control behaviors. The model is compared with existing literature. Finally a working prototype is built to verify our simulation results.

Speech Title: Organic and Silicon based flexible Electronics
Abstract: Flexible electronics becomes now a major research domain due to a fast growing market. The overall revenue of wearable technology was $38 billion in 2017 and it is expected to grow over $85 billion in 2022. The dominant sectors will be healthcare and medical, fitness and wellness. Silicon based electronics showed its ability to be highly flexible, reaching less than 1mm curvature radius and then meaning the possibility to be fold nearly in half, to be stored and reused when re-flattened. With their very low Young modulus, organic materials are considered fitting perfectly the need of flexibility. The main purpose is then to fabricate electronic devices using organic materials only. Best performance Organic Field Effect Transistors (OFET) are P-type. However the most efficient electronics needs both N-type and P-type transistors. Then, huge research is done to increase the performance of N-type OFETs. The fabrication of such transistors involve different technologies. Of course, the chosen technology has to be made easily at the lowest cost possible, on large area, at compatible with flexible substrate temperature. Deposition in solution, particularly printing technology, fulfill the requirements of easy process, low cost and compatibility with flexible substrate. Among several printing technologies, inkjet printing drop-on-demand technology is the most promising. The talk will give a review of main results on silicon and organic based flexible electronics.

Speech Title: TFTs for Active Matrix: From Silicon to Oxides and New Materials
Abstract: Thin-film Transistor (TFT) is one of key compoments for flat-panel displays (FPDs). Amorphous silicon (a-Si:H) TFTs have excellent uniformity for large area application; however, field effect mobility and reliability of the TFTs are not sufficient to adress an organic light emitting diode (OLED) display. Excimer laser annealing is used to crystallize amorihous Si into poly-Si (LTPS). Since field effect mobility of LTPS TFT is over 100 cm2/Vs, it is widely used for high-definition and small size FPDs for smartphone. Recently, metal oxide semiconductors, such as InGaZnO (IGZO), have attracted particular attention for TFT applications owing to its high field effect mobility of over 10 cm2/Vs, steep subthreshold swing (S.S.) , extremely low off current, large-area uniformity, and good bias stress stability. In this presentation, recent TFT technologies for active matrix and flexible displays will be discussed including a heterointegration of LTPS and oxide TFTs.

Abstract: In this paper, a multifunctional flexible strain sensor basing on hydrogel was reported. A double network was designed by in-situ polymerization of [2-(methacryloyloxy) ethyl] dimethyl-(3-sulfopropyl) ammonium hydroxide (SBMA) in bacterial cellulose nanofibers (BCN) aqueous dispersion. Due to the whole biomass based materials, the obtained hydrogel PSBMA@BCN shows excellent biocompatibility. Benefiting from the numerous zwitterionic functional groups, the PSBMA@BCN hydrogel also shows great anti-swelling and self-adhesion performance. The resistance of PSBMA@BCN hydrogel shows almost linear dependence on the strain ranging from 0 to 150%. Based on the hydrogel sensor, an intelligent communication system is developed to achieve information transmission. The assembled PSBMA@BCN flexible wearable device can precisely respond to target movement and output signals in real time so that the hydrogel can play a role in monitoring and identifying different target movement. More significantly, the anti-swelling properties make the wearable electronic device can be applied even in underwater condition, the hydrogel sensor can not only realize real-time monitoring and identification of target movement, but can also achieve intelligently underwater communication through the combination of computer programming and circuit design. As such, the biocompatibility hydrogel sensor has broad application prospects in underwater environment, providing a promising route to promote the development of next-generation wearable devices.

Abstract: In recent years, flexible sensors gain much attentions due to its capability of mimicking human skins for perceiving, distinguishing, and transmitting various external stimuli, which have promising applications in human-machine interfaces, internet of things and structural health monitoring. To accomplish the aforementioned applications, not only high sensitivity, fast response speed and mechanical robustness are demanded for the sensors, but also a highly efficient and scalable fabrication method is desired for wide adoption of the sensors. In this talk, laser-based microfabrication method was developed to fabricate flexible sensors, which has been proved to be high-throughput and scalable. Firstly, a laser direct writing technique is developed to fabricate high-performance strain sensors directly on flexible substrates including polyimide, Ecoflex film, etc.. Then, a laser microengineering method is developed to introduce microstructures into flexible pressures for enhanced sensitivity and response time. Finally, the potential applications of the sensors in status monitoring of hydrogen storage vessel for fuel cell autocycle is presented.
