Gao, 31, is currently a postdoctoral fellow at UC Berkeley. There he continues to work on technologies similar to those developed by the Center for Wearable Sensors, led by Wang here at the Jacobs School.
In January 2016, he was first author on a Nature paper titled "Fully integrated wearable sensor arrays for multiplexed in situ perspiration analysis." The study received broad media coverage, including in The New York Times, The Wall Street Journal, Scientific American, IEEE Spectrum, Wired and many other outlets.
Essentially, Gao and colleagues built a sweatband that combines sensors with electronic processors and a Bluetooth transmitter on a flexible printed circuit board. The device wirelessly transmits data about what's in your sweat to an app on your cell phone.
