Performance comparison of hybrid and non-hybrid contact mode triboelectric energy harvester

Abstract

Energy harvesting technology has been developed over the years due to the demand for low power electronic applications. One of the types of energy harvester is the triboelectric transduction. Triboelectric energy harvesters have been developed and widely being adopted in this energy harvester technology. Many factors need to be considered while applying this mechanism such as materials, surface area and roughness, the gap between two layers and input parameters. In designing the triboelectric energy harvester, there are four types of modes namely contact mode, sliding mode, free standing mode and single electrode. This paper demonstrated a feasible design of cantilevered structured for non-hybrid and hybrid triboelectric energy harvester mechanism to compare the effectiveness of the output between two different working mechanisms as well as parameters such as the effect of materials, the effect of mass at different conditions. A cantilevered structure triboelectric nanogenerator (TENG) been demonstrated and studied the effect of different input frequencies and load resistance. A maximum peak voltage of 2.118 V at 40 Hz. Further strategies to improve the performance of the harvester can also be done and can be applied to low power electronic applications.
