Abstract
Triboelectric nanogenerators have received significant research attention in recent years. The energy harvesting performance of triboelectric nanogenerator can be enhanced via more efficient structural and material designs. Here, we develop novel magnetic capsulate triboelectric nanogenerator (MC-TENG) devices to harvest electrical energy under various external excitations. MC-TENG uses a magnetic oscillation system to guide oscillating dielectric capsules within a conductive shield. Steel spring connectors are then utilized to maximize the oscillations and higher power density. Experimental studies is conducted to investigate the electrical performance of MC-TENG under cyclic loading. The output power of the developed nanogenerators reached 400 μW. The proposed MC-TENG concept provides an effective method to harvest electrical energy from low-frequency and low-amplitude oscillations.
