尽管介电弹性体致动器（DEA）作为一种实用的软致动器具有良好的特性，但其运行所需的高电压阻碍了实用 DEA 的成功制造，也就是说，高电压的产生需要笨重且昂贵的电源。 DEA 复杂的形状变化运动（例如振荡形状变化）的感应甚至需要更庞大和更昂贵的多用途电源。这是一个需要克服的严重的现实问题。然而，在我们最新的研究中，我们可以构建一个简单的 DEA 系统，该系统仅在恒定电压下表现出相对复杂且自主的振荡形状变化，尽管所需的电压很高。这一成功结果必须扩大 DEA 作为实用软执行器的潜在用途。
Despite the promising characteristics of Dielectric Elastomel Actuator (DEA) as a practical soft actuator, the need of high voltage for its operation prevents the successful fabrication of a practical DEA, that is, the high voltage generation takes a bulky and costly power supply. Induction of complex shape change motion of DEA such as oscillatory shape change takes even a more bulky and costly multipurpose power supply. It is a serious practical issue to be overcome. In our latest study, however, we could build a simple DEA system which exhibited a relatively complex and autonomous oscillatory shape change merely under a constant voltage, though the voltage needed was high. This successful outcome must broaden the potential usefulness of DEA as a practical soft actuator.
