我们提出了一种无线软致动器控制热毫米波辐射。致动器由密封在软波纹管中的低沸点液体组成。通过照射高功率的毫米波，液体可以被蒸发以产生强大的机械力。我们的特点是从波纹管提取的力和功作为液体体积和温度的函数。然后，我们展示了无线驱动的波纹管上照射毫米波。我们还评估了它的动态响应，通过调制毫米波。我们的方法提供了新的用途和设计空间的软执行器。
We propose a wireless soft actuator controlled thermally by millimeter-wave irradiation. The actuator is composed of low boiling point liquid sealed in a soft bellows. By irradiating high-power millimeter-waves, the liquid can be evaporated to generate a strong mechanical force. We characterize the force and work extracted from the bellows as a function of the liquid volume and temperature. We then demonstrate the wireless actuation by irradiating a millimeter-wave on the bellows. We also evaluate its dynamic response by modulating the millimeter-wave. Our approach provides novel usage and design space of soft actuators.
