Inchworm actuator
WebTypical bionic piezoelectric inchworm actuators utilize at least two clamping piezo-stacks (PZTs) and one driving PZT to achieve bi-directional actuation, resulting in complex structures, complicated electronic systems, and high cost. WebA new piezoelectric inchworm actuator based on the principle of flexible amplification is developed in this paper. In the moving mechanism of the actuator, its clamping mechanism adopts symmetrical lever amplification structure, and its middle drive mechanism uses compound bridge structure.
