Terasaki Talks Presents: “New Materials and Devices for Soft Electronics”, Presenter: Dr. Sheng Xu

Abstract: Soft electronic devices that seamlessly integrate with the human body represent an essential trend for future consumer electronics and mobile healthcare. Combined strategies of advanced microfabrication and materials design allow the integration of various components and devices on a soft platform, resulting in functional systems with minimal constraints on the human body. In this presentation, I will demonstrate the first of its kind a multilayered stretchable multichannel patch that can sense a collection of signals from the human skin in a wireless mode. Additionally, existing wearable electronic devices are limited to sensing signals on the skin surface. I will show a stretchable ultrasonic patch that adds a new third dimension to the detection range of existing soft electronics. Ultrasound waves can penetrate the skin and noninvasively capture dynamic events in deep tissues, such as blood pressure and blood flow waveforms in central arteries and veins. For the power source, I will demonstrate a protocol for growing large area single-crystal hybrid halide perovskites for high performance flexible solar cells. This soft platform holds profound implications for a wide range of applications in personal electronics, sports medicine, defense, and clinical practices.

Biography: Dr. Xu is currently an assistant professor at UC San Diego. He received his B.S. in Chemistry and Molecular Engineering from Peking University and Ph.D. in Materials Science and Engineering from Georgia Institute of Technology. He worked as a postdoctoral researcher in the Department of Materials Science and Engineering at the University of Illinois at Urbana-Champaign. His group is interested in developing soft wearable electronics for health monitoring and human-machine interfaces. His research has been presented to the Congressmen and Congresswomen as testimony of NIH extramural research during a Congressional Hearing. He has been recognized by a number of awards, including NIH Maximizing Investigators’ Research Award, NIH Trailblazer Award, Wellcome Trust Innovator Award, MIT Technology Review 35 Innovators Under 35, SPIE DCS Rising Researchers, IEEE Sensor Council Early Career Technical Achievement Award, and MRS Outstanding Young Investigator Award. He is a Kavli Fellow of the National Academy of Sciences and a Frontier of Engineering of the National Academy of Engineering. He serves Nano Research as a Young Star Editor.
