Flexible systems for wearable physiological monitoring applications

Abstract

A flexible-system integration strategy is demonstrated which merges plastic based sensors that interface with the skin with silicon integrated circuits consolidated on a flexible printed circuit board for complex signal processing. As an example application, we present a flexible fully-integrated and wireless perspiration biosensor that accurately and simultaneously measures a panel of electrolytes and metabolites in sweat in real-time while calibrating the sensors' response against the change in skin temperature.
