Caltech's New Health Tracker Runs on Sweat and Sunlight

Caltech researchers have developed a groundbreaking health monitoring device that operates without batteries, instead harnessing energy from sweat and sunlight. This innovative wearable, detailed in a study published in *Nature*, features a flexible, stretchable sensor array that can monitor various health metrics like glucose, lactate, and sweat rate. The device uses a biofuel cell to convert sweat into electrical energy and a solar cell for additional power, ensuring functionality even when the wearer isn't sweating. This dual-energy approach not only makes the device self-sustaining but also environmentally friendly, reducing the need for frequent charging or battery replacements. The technology promises to revolutionize health monitoring by providing continuous, real-time data without the constraints of traditional power sources, potentially impacting fields from sports science to medical diagnostics.
