An epidermal electrode based triboelectric walking energy harvester for wearable wireless sensing applications

Harvesting bio-kinetic energy using a triboelectric nanogenerator(TENG)is one of the promising routes to solve the sustainable energy supply problem for wearable electronics.However,additional materials,complex fabricating processes or specific mechanical structures are needed for existing TENGs to harvest bio-kinetic energy.Besides,they need to be tightly attached to the human body,which may result in detachment and malfunction under tense human motion.Herein,an intrinsic epidermal electrode-based TENG(E-TENG)is proposed to harvest human walking energy.The wearing shoes and ground are used as tribo-materials,and the human epidermis is used as the back electrode of the E-TENG.Compared with the traditional TENGs,the E-TENG does not need any additional tribo-materials and complex mechanical structures.Under optimal conditions,the voltage output of E-TENG can reach 914 V.E-TENG has been used as a self-powered warning sensor and pedometer sensor for demonstration.Furthermore,E-TENG based self-powered wireless sensor system has been developed using a newly designed micro energy electronic switch(MEES).Ambient ultraviolet intensity,temperature and humidity information can be monitored and then transmitted to mobile phone every 3.5 min,demonstrating great potential for widespread wearable applications.
