Abstract

A triboelectric energy harvester with a long-lasting and steady output was developed by using an escapement mechanism to induce a much larger torque after storing the irregular input motion as elastic energy in a spiral torsion spring. The escapement mechanism-based triboelectric nanogenerator (EM-TENG) consists of the spiral torsion spring, escapement part, and a torsional resonator for regular operation and frequency up-conversion using freestanding mode interdigitated electrodes. Under only 5 s of input motion, the EM-TENG produces long-lasting and steady output power for 110 s by using the escapement mechanism.
