UC San Diego engineers develop a sweat-powered finger wrap for continuous health monitoring, with potential for closed-loop treatment delivery.
Engineers at UC San Diego have created a sweat-powered wearable finger wrap that monitors vital chemicals, including glucose and vitamins, from fingertip sweat. Published in *Nature Electronics*, the device uses biofuel cells to convert sweat into electricity, fueling sensors for continuous health monitoring. Researchers aim to develop a closed-loop system that not only tracks biomarkers but also delivers treatments, such as insulin for diabetes, based on the data collected.
