Wei Gao is current an Assistant Professor of Medical Engineering at California Institute of Technology. He received his PhD in Chemical Engineering at University of California, San Diego in 2014 as a Jacobs Fellow and HHMI International Student Research Fellow. In 2014-2017, he was a postdoctoral fellow on wearable devices with professor Ali Javey at the University of California, Berkeley. He has authored over 60 journal publications and received several awards such as 2016 MIT Technology Review Top 35 Innovator Under 35 (TR35), 2015 ACS DIC Young Investigator Award, MRS Graduate Student Award, 2013 AICHE Bionanotechnology Graduate Student Award, 2012 Chinese Government Award for Outstanding Self-financed Students Abroad. His research interests include flexible electronics, biosensors, naonomachines and nanomedicine.

Fully-Integrated Wearable Sensor Arrays for Multiplexed In Situ Perspiration Analysis [BPN818]
A flexible and wearable microsensor array is described for simultaneous multiplexed monitoring of heavy metals in human body fluids. Zn, Cd, Pb, Cu, and Hg ions are chosen as target analytes for detection via electrochemical square wave anodic stripping voltammetry (SWASV) on Au and Bi microelectrodes. The oxidation peaks of these metals are calibrated and compensated by incorporating a skin temperature sensor. High selectivity, repeatability, and flexibility of the sensor arrays are presented. Human sweat and urine samples are collected for heavy metal analysis, and measured results from the microsensors are validated through inductively coupled plasma mass spectrometry (ICP-MS). Real-time on-body evaluation of heavy metal (e.g., zinc and copper) levels in sweat of human subjects by cycling is performed to examine the change in concentrations with time. This platform is anticipated to provide insightful information about an individualís health state such as heavy metal exposure and aid the related clinical investigations.
