Rolling friction contact-separation mode hybrid triboelectric nanogenerator for mechanical energy harvesting and self-powered multifunctional sensors

Based on rolling contact electrification, electrostatic induction and Faraday's Law a hybrid contact-separation mode nanogenerator (HCS-TENG) is attained. The output performances of HCS-TENG in various rotation speeds have been studied systematically, it can greatly broaden frequency band in mechanical energy harvesting and exhibit the ultra-robustness. In addition, utilizing the output signal's intrinsic characteristics of CS-TENG, a self-powered multifunctional sensor has been achieved.241
