A thermally driven liquid crystalline elastomer bending actuator was prepared with extended cycling capabilities. This device operated with strain rates of 1 Hz displacement and 0.13 Hz recovery starting from 25.1 degree(s)C to a maximum of 150 degree(s)C. The device is a bending actuator having a multilaminated material structure. Observed displacements were lower than previous freestanding liquid crystalline elastomer films due to the constraints imposed on the liquid crystalline elastomer by the device architecture. A device operated with low power of less than 2 W and cycled over a 1000 times successfully.
