A triboelectric energy harvester converts mechanical energy to electrical energy, which is then collected and used to charge a rechargeable battery. This battery may be used to power small electronics devices for a myriad of applications such as temperature and humidity sensors, accelerometer or GPS tracking devices. In this paper, mathematical model of sliding mode triboelectric energy harvester has been developed to predict the harvested energy under mechanical motion, constant speed and accelerated motion. Numerical results reveal that harvested energy depends upon the type of motion, dielectric constant and surface charge density of triboelectric material. Further, experimental study has been conducted to validate the numerical result, and there is significant error between numerical and experimental result. Experimental setup will be further improved.
