Efficient Interfacial Electrical Energy Extraction of a Triboelectric Nanogenerator by the Charge Lock‐Free Strategy

at 70 MΩ. Furthermore, the equivalent circuit model is analyzed and it is found that the capacitance change of the LF-TENG is twice that of traditional devices, which is the main factor for the increase in the output power. This study provides valuable insights into efficient electrical energy extraction from sliding frictional interfaces and paves the way for the development of low-frequency mechanical energy-collection technologies.
