【 摘 要 】

This paper reports an ionic polymer-metal composite (IPMC) soft actuator that is controlled and powered in a wireless manner. IPMC is an ionic electroactive polymer (EAP) that can be actuated at a low voltage, fast response and miniaturized, therefore, attracts significant interest that have led to extensive investigations, especially for biomedical application. The device design utilizes magnetic resonant coupling as the wireless powering scheme. A planar based LC receiver circuit and DC rectifier circuit are fabricated using double sided and single sided copper-clad flexible polyimide sheets, respectively. The fabricated IPMC cantilever is bonded to the DC rectifier circuit and performs unimorph motion when the exposed magnetic field (generated by the transmitter circuit) matches the resonant frequency of the LC receiver circuit, ∼25 MHz. Experiment wireless operation of the fabricated LC receiver circuit shows a maximum induced DC voltage of ∼2.3 Vdc. The cantilever deflection is measured as 66 μm at ON-OFF activation cycle with 0.6 W RF output power.
