Abstract
Wearable health monitoring platforms require advanced sensing modalities with integrated electronics. However, current systems suffer from limitations related to energy supply, sensing capabilities, circuitry regulations and large form factors. Here, we report an autonomous and continuous sweat sensing system that operates on a fingertip. The system uses a self-voltage-regulated wearable microgrid based on enzymatic biofuel cells and AgCl-Zn batteries to harvest and store bioenergy from sweat, respectively. It relies on osmosis to continuously supply sweat to the sensor array for on-demand multi-metabolite sensing and is combined with low-power electronics for signal acquisition and wireless data transmission. The wearable system is powered solely by fingertip perspiration and can detect glucose, vitamin C, lactate and levodopa over extended periods of time.
