[AllUsers-ISR] Palestra / Talk on Self Powered Wearable Devices, Professor Mehmet Ozturk NC State University

[Mahmoud Tavakoli]

Dear All, 



On 28 of October, 11h in ISR amphitheatre, we will have an attractive talk from Professor Mehmet Ozturk from North Carolina State University on Self-Powered Wearable Electronics for health and Performance monitoring. Professor Ozturk served as the director of NC State’s Nanofabrication Facility, and as the Deputy Director of the ASSIST Centre ( Centre for Advanced Self-Powered Systems of Integrated Sensors and Technologies). He is currently doing his sabbatical at Electrical Engineering Department of University of Coimbra. 




All FCTUC community, professors, researchers and students are invited to assist this talk. 














Self-Powered Wearable Electronics for Health and Performance Monitoring 

Mehmet C. Ozturk, Professor, Electrical & Computer Engineering, NC State University 




Wearable electronics for health and performance monitoring have seen a significant rise in popularity in recent years due to their ability to provide real-time, personalized insights into various aspects of an individual's physical condition. Devices such as smartwatches, fitness trackers, and smart clothing are equipped with sensors that monitor heart rate, activity levels, sleep patterns, and even stress indicators. This technology empowers users to take control of their health by offering data that helps improve fitness, monitor chronic conditions, and detect potential health issues early. Their importance lies in the fact that they bridge the gap between individuals and healthcare providers, enabling proactive health management and a more informed, data-driven approach to wellness. 

A key advancement in this field is the development of self-powered wearable electronics, which utilize energy harvested from the human body or the ambient environment. Such devices are especially beneficial for continuous, long-term monitoring in applications like chronic disease management, where uninterrupted data collection is vital. By harvesting energy from body heat or motion, these devices offer a more seamless and sustainable user experience, eliminating the need for frequent charging and ensuring uninterrupted monitoring of vital signs. 

This talk will present an overview of the research conducted at the Center for Advanced Self-Powered Systems of Integrated Sensors and Technologies (ASSIST) at North Carolina State University, a multi-institutional center funded by the National Science Foundation and led by the Electrical and Computer Engineering Department at NC State. The talk will also present an overview of Professor Ozturk's work on flexible thermoelectric harvesters, utilizing EGaIn liquid-metal interconnects to capture body heat for self-powered operation. Further details on flexible thermoelectric devices will be explored in a follow-up seminar in November. 









Mehmet C. Ozturk received his BS degree in Electrical Engineering from Bogazici University in Istanbul, Turkey in 1980. He received his MS degree from Michigan Tech in 1983 and his PhD degree from NC State University in 1988. After graduation, he joined the faculty in the Department of Electrical and Computer Engineering, where he is now serving as a Professor. 



His early research focused on advances in design and manufacturing of transistors for nanoscale CMOS. Specifically, his work focused on selective epitaxy of Si, SiGe, and Si:C for MOSFET channel and junction engineering. His group was first to propose the use of selective SiGe epitaxy in recessed and elevated source/drain junctions. This work also resulted in the first demonstration of self-aligned contacts to SiGe alloys, or germanosilicides, a term coined by his group. Starting with Intel’s 90 nm CMOS, the selective SiGe source/drain technology was widely adopted in CMOS manufacturing, and it is still in use today in state-of-the-art FINFETs. Dr. Ozturk was named a fellow of the IEEE in 2009 for his contributions in Si and SiGe Epitaxy and their applications in advanced MOS field effect transistors. 



Starting 2010, Dr. Ozturk’s research interest shifted to flexible thermoelectric devices and their use in heat harvesting from the human body. His group was first to propose the use of EGaIn liquid metal as an interconnect material in flexible thermoelectric devices, a technology which he patented in 2019. His devices were used in self-powered wearable electronics developed by the Center for Advanced Self-Powered Systems of Integrated Sensors and Technologies (ASSIST), funded by National Science Foundation. His more recent work focuses on developing a wearable core-body temperature sensor relying on EGaIn and flexible thermoelectric devices. 



Dr. Ozturk served as the director of NC State’s Nanofabrication Facility, and as the Deputy Director of the ASSIST Center.
