Abstract: Wearable 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 systems with minimal constraints on the human body. We
have demonstrated a skin-mounted multichannel health monitor that can sense local field
potentials, temperature, strain, acceleration, and body orientation. Integrating ultrasonic
transducers on this stretchable platform adds a third dimension to the detection range by
launching ultrasound waves that reach well underneath the skin. The ultrasound waves allow
capturing a wide range of dynamic events in deep tissues such as blood pressure in central
arteries and veins. This technology holds profound implications for continuous and
noninvasive sensing, diagnosis, and treatment of chronic diseases.
Biography: Sheng Xu is currently an assistant professor in the Department of
Nanoengineering at UC San Diego. He received his B.S. in Chemistry and Molecular
Engineering from Peking University in Beijing, China, and Ph.D. in Materials Science and
Engineering at Georgia Institute of Technology. He worked as a postdoctoral research
associate in Frederick Seitz Materials Research Laboratory at the University of Illinois at
Urbana-Champaign, where he developed advanced stretchable electronic systems for
healthcare and energy applications. His research group currently focuses on crystalline
material growth for high-performance energy devices and biointegrated electronics for
human-machine interface and health monitoring. His research has been recognized by a
series of awards, including the MIT Technology Review Top Innovators Under 35, NHLBI
Technology Development Award, 3M Non-Tenured Faculty Award, the TSMC Research Gold
Award, and the International Union of Pure and Applied Chemistry Prize for Young Chemists.
This event is open to anyone who has interests in biomedical technologies. Light snacks and
refreshments will be provided.
