摘要

Nowadays,17％ global electricity and 70％ renewable electricity are from hydropower.Despite its abundance and sustainability,converting hydropower to electricity always needs turbines and magnets to make use of electromagnetic induction [1].Unlike electromagnetic induction,direct contact between materials can also generate electric charges.This contact electrification or triboelectricity phenomenon was discovered more than 2000 years ago,but its application in energy-related fields has not been greatly explored until recently,when Wang et al.developed a triboelectric nanogenerator (TENG) to harvest the kinetic energy from water droplets to produce electricity,which allows us to access hydropower in a wide range of working environments [2].
