Single wearable sensing energy device based on photoelectric biofuel cells for simultaneous analysis of perspiration and illuminance.

Wearable electronics are essential for the construction of epidermal energy supply and portable healthcare devices. Herein, a self-powered wearable electronic device based on a photoelectric biofuel cell has been introduced for the first time to simultaneously detect the perspiration lactate and monitor the ambient illuminance depending on independent parameters. The functions of harvesting energy, detection of body function and monitoring of ambient have been merged into a single wireless sensor. This novel design may provide a wide range of smart and exciting wearable electronics.
