sNails: sweat-sensing nails for unobtrusive, wearable microfluidic sweat monitoring from the dorsal distal phalanges

Hi, I’m Noelle! I’m an recent PhD grad in Electrical Engineering at UC Berkeley, where I was advised by Ali Javey and studied human eccrine sweat as a biosensing target for medical and athletic applications. I was affiliated with the Berkeley Sensors and Actuators Center and supported by an NDSEG Fellowship. More broadly, I am interested in flexible electronics, electrochemical sensing, and embedded systems.
Previously, I received a B.S. in Electrical Engineering from Caltech, where I worked on biomedical sensing with Axel Scherer.
Below you can find my published research projects and other shared ideas.
