The emerging multifunctional flexible electronic-skin for establishing body-electric interaction can enable real-time monitoring of personal health status as a new personalized medicine technique. A key difficulty in the device design is power supply. Here self-powered wearable noninvasive perspiration analysis has been realized on basis piezo-biosensing unit matrix enzyme/ZnO nanoarrays. detect lactate, glucose, uric acid, and urea perspiration, no outside electrical supply or battery used biosensing process. piezoelectric impulse units serves data biosensor. working mechanism be ascribed to piezoelectric-enzymatic-reaction coupling effect nanowires. real-time/continuously monitor physiological state runner through analyzing his skin. This approach promote development new-type body electric electronic-skin.
