Detailed investigation of sinusoidal vibration on triboelectric energy harvester

Abstract

ABSTRACT The triboelectric energy harvester (TEH) could power small electronic devices, including temperature sensors, GPS trackers, accelerometers, and humidity sensors. An experimental and simulation investigation on the harvesting of sinusoidal mechanical vibration utilizing a triboelectric mechanism is presented in this article. According to numerical results, the amount of energy harvested depends on many input elements such as movement of the upper electrode, external resistance, phase angle, contact area, and thickness of the dielectric layer. The influences of the dual parameters, including the dielectric thickness, contact area, external resistance, phase angle, and vibration frequency on electrical output, were investigated systematically. The stability and durability test are performed for fabricated TEH. Simultaneously, a bridge rectifier has been used to convert produced A.C. signals into D.C. signals. The output voltage is stored in capacitors of various sizes (0.47, 3.3, 10, 22, 47 µF) with no load resistances. The feasibility of the developed TEH is proved by lighting up 35 red Light-Emitting Diodes (LEDs).
