University of Arizona (UA) engineers have developed personalized biosymbiotic devices that can operate without recharging.

The three-dimensionally-printed wearables are based on body scans of wearers, and can function continuously via wireless power transfer combined with compact energy storage.

The custom-fitted devices can wrap around various body parts, with specialized sensors positioned to measure otherwise unattainable physiological parameters.

The devices are sufficiently accurate to detect body temperature changes caused by walking up a single flight of stairs.

UA's Philipp Gutruf said, "These devices are designed to require no interaction with the wearer. It's as simple as putting the device on. Then you forget about it, and it does its job."
