Development and application of triboelectric nanogenerator based on waste tea
In order to improve the output performance of TENG,by-products generated during tea processing were selected as materials,and the influence of the particle size was systematically studied.The results show that the electrical output performance of TENG increases with the increase of the number of tea powder par-ticles.When the number of tea powder particles is 400,the open-circuit voltage,short-circuit current,and out-put power reach 275 V,9 μA,and 459.51 μW,respectively.The output power density at an impedance of 10 MΩ can reach 45.951 mW·m-2.In addition,the prepared TENG can light up 120 commercial LEDs and has good capacitor charging ability,demonstrating good performance in power supply for electronic devices and wireless sensors.
