Owing to their adaptive interfacial properties, soft actuators can be used to perform more delicate tasks than their rigid counterparts. However, traditional polymeric soft actuators rely on energy conversion for actuation, resulting in high power input or slow responses. Here we report an electrical plant-based actuator that uses a conformable electrical interface as an electrical modulating unit and a Venus flytrap as an actuating unit. Using frequency-dependent action-potential modulation, accurate on-demand actuation is possible, with response times that can be tuned to 1.3 s and a power input of only 10⁻⁵ W. The actuator can be wirelessly controlled using a smartphone. It can also be installed on a range of platforms (including a finger and a robotic hand) and can be used to grasp thin wires and capture moving objects.

由于其自适应界面特性，软致动器可用于执行比刚性对应物更精细的任务。然而，传统的聚合物软执行器依赖于能量转换来驱动，导致高功率输入或缓慢响应。在这里，我们报告了一种基于电气设备的执行器，该执行器使用符合要求的电气接口作为电气调制单元，并使用捕蝇草作为执行单元。使用频率相关的动作电位调制，可以实现精确的按需驱动，响应时间可以调整到 1.3 秒，功率输入仅为 10 ^-5 W. 可以使用智能手机无线控制执行器。它还可以安装在一系列平台上（包括手指和机械手），可用于抓取细线和捕捉移动物体。
