A sweat-powered finger wrap could make monitoring a person's health as easy as wearing a Band-Aid, researchers report.

Engineers have designed an electronic finger wrap that not only derives its energy from fingertip sweat but also monitors vital chemical levels, including glucose, vitamins, and even drugs. This breakthrough has the potential to revolutionize health monitoring and empower individuals to take control of their well-being effortlessly.

“This is automatic health monitoring at your fingertips,” said co-lead investigator Shichao Ding, a postdoctoral researcher at the University of California, San Diego's Jacobs School of Engineering. “The wearer can be resting or asleep, and the device can still harvest energy and track biomarker levels.”

A sweat-powered wearable has the potential to make continuous, personalized health monitoring as effortless as wearing a Band-Aid.

Imagine a tiny wearable device that can monitor your health using nothing but your sweat. Engineers at the University of California San Diego have developed a finger wrap that does just that. This device can track important health markers,
