Investigation of power generation based on stacked triboelectric nanogenerator

This paper investigated the stacked triboelectric nanogenerator. It was found that the stacked spring construction could enlarge the output voltage, current and the amount of transferred charges of one single generator. Specifically, by employing a 3-layer-stacked triboelectric nanogenerator, a 430 V output voltage was obtained under a 5 Hz periodic impact. Furthermore, thanks to the duration expansion of the stacked device, a continuous square wave output higher than 10 V was produced, with an external frequency of 3 Hz. (C) 2013 Elsevier Ltd.
