A super-flexible and lightweight membrane for energy harvesting

This paper presents a super-flexible and lightweight membrane for energy harvesting. Based on the combined effect of contact electrification and electrostatic induction, a triboelectric energy harvester (TEH) was designed, simulated, fabricated, and tested. Thanks to the specially designed structure and electrode pattern, this super-flexible TEH can produce root mean square (RMS) voltage of 33.8 V and average power of 40.7 μW. Moreover, this membrane is capable of harvesting multi-type mechanical energy, including different motion styles and various contacted materials.
