✦ Synopsis

Currently, there is a strong and increasing demand for electric actuators. Applications include the automotive, aircraft and space industries. The paper presents a proof-of-concept design of a large displacement and medium force inchworm actuator. The technology considered uses an electrostrictive mechanism that ''walks'' inside an outer casing. This motion emulates an inchworm, summing small steps to achieve large displacements. The detailed design of the electrostrictive inchworm actuator was performed using finite element analysis. A prototype was constructed and tested and the performance matched well with the numerical simulation results.
