A performance study on the drum-type energy harvesting device based on triboelectric nanogenerator

A drum-type energy harvesting system utilizing a triboelectric nanogenerator (TENG) has been developed to provide power for wireless health monitoring devices. The electrical performance and structural reliability are assessed through simulation. Experiments examine the effect of contact area and vibration acceleration on the electrical output of the electrode pair. Experimental results suggest that the peak-to-peak value of the conversion circuit voltage could reach 39.9 V, and the output power of a single electrode pair for one cycle can reach 17.74 mu W. The total output power of the drum-type TENG device, which consists of eight electrode pairs, is 141.92 mu W. This paper elucidates a method for powering low-power sensors or arrays of LEDs.
