Miniature driving circuit for electroactive polymer actuator

The invention discloses a miniature drive circuit for an electroactive polymer actuator. The drive circuit comprises a high-energy-density low-voltage battery, the high-energy-density low-voltage battery is connected with a feedback sensing unit after sequentially passing through a control module, a switching circuit and the electroactive polymer actuator, and the feedback sensing unit is used for detecting the running state of the actuator, and performs feedback control on the on-off of the driving circuit; and the loading time of the voltage on the electroactive polymer actuator is controlled by using a switching signal, and the maximum charging electric quantity of the actuator, the deformation size of the actuator or the driving force are measured through the feedback sensing unit to carry out feedback control on the pulse width. The drive circuit is small in size and convenient to use, and meets the requirements of carrying and testing anywhere. 本发明公开了一种电活性聚合物执行器用小型驱动电路，包括高能量密度低压电池，高能量密度低压电池依次经控制模块、开关电路和
