为了驱动电活性聚合物（EAP）材料并随后控制其应变产生，对电力电子和驱动电路的需求非常突出。在这封信中，作者展示了电活性聚合物的自发驱动，仅需要直流电即可产生交流响应。 EAP 的这种直流转交流响应是通过在离聚物 Nafion (TM) 上沉积有效的电催化剂（即铂）来实现的。将涂覆的离聚物浸入酸性甲醛溶液中。施加的直流电压将在系统中产生电流振荡，从而导致执行器振荡弯曲。 (c) 2007 年美国物理研究所。
To drive the electroactive polymer (EAP) materials and subsequently control their strain generation, the need for power electronics and driving circuits has been eminent. In this letter the authors demonstrate a spontaneous actuation of an electroactive polymer that requires only dc power to produce its ac responses. Such a dc-to-ac response of the EAP was achieved by the deposition of an effective electrocatalyst, i.e., platinum, on an ionomer, Nafion (TM). The coated ionomer was immersed into an acidic formaldehyde solution. An applied dc voltage will produce current oscillations in the system, and therefore oscillating bending of the actuator.
