抄録

A gelatinized ionic liquid of [TMPA] + [TFSI] suspended in a polymer is proposed for the first time as a dielectric material for micro-electromechanical systems (MEMS) vibrational energy harvesters. Owing to the high-density charges in the electrical double layer (EDL) formed at the gel/electrode interface, a high contrast of capacitance modulation is realized, thereby enhancing the electrostatic induction current. A typical current of 4.6 µA rms cm -2 is experimentally confirmed for a 10 kΩ load resistance connected to a DC voltage of 1.5 V, which is thought to be 86-fold greater than that produced by an energy harvester with a simple air-gap.
