Perovskite power for wearable sweat sensors

A wireless wearable biosensor that is powered by a flexible perovskite solar cell can be used to continuously monitor a person’s physicochemical data — glucose, pH, sodium ions, sweat rate and skin temperature — across indoor and outdoor activities. The photograph on the cover shows the wearable sweat sensor attached to an arm.
