Abstract

In light driven liquid crystal network (LCN) actuators, large performance improvements can be obtained by varying the molecular director through the thickness of the film actuator. Experiments show that these systems are efficient and have an internal work density of 50kJ/m3, orders of magnitude larger than that of the uniaxial planar film with the same chemical composition. The material is easy to process using standard photopatterning techniques and can be easily integrated in microsystems.
