BIOENGINEERING SEMINAR
Abstract:
Soft electronic devices that can acquire vital signs from the human body represent an important trend for healthcare. Combined strategies of materials design and advanced microfabrication allow the integration of a variety of components and devices on a stretchable platform, resulting in functional systems with minimal constraints on the human body. In this presentation, I will demonstrate a wearable multichannel patch that can sense a collection of signals from the human skin in a wireless mode. Additionally, integrating high-performance ultrasonic transducers on the stretchable platform adds a new third dimension to the detection range of conventional 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. This stretchable platform holds profound implications for a wide range of applications in consumer electronics, sports medicine, defense, and clinical practices.

Professor Sheng Xu was appointed in July 2015 as a member of the faculty in the Department of NanoEngineering at UC San Diego. Xu was a postdoctoral research associate in Frederick Seitz Materials Research Laboratory from 2011 to 2015 at University of Illinois at Urbana-Champaign, where he developed advanced wearable electronic systems for healthcare and energy applications. He received his Ph.D. in Materials Science and Engineering in 2010 at Georgia Institute of Technology, and was the recipient of the 2011 IUPAC Prize for Young Chemists for his Ph.D. research on oxide nanowire arrays for energy sciences. He obtained his B.S. in Chemistry and Molecular Engineering from Peking University in Beijing, China in 2006.
