Paper Abstract

Dielectric polymer actuators promise to revolutionize user interfaces by enabling surface actuators that can change surface shape and give tactile feedback from a thin layer. We have realized a programmable surface actuator, based on non-pre-stretched silicone, which is capable of realizing large freeform surface deformations from relatively thin layers, while maintaining very good control over the shape of the actuated surface. Moreover, the actuator setup allows the use of a thin, stiff top layer, which addresses friction and stickiness problems commonly associated with using soft elastomers in tactile displays. Out-of-plane deformations exceeding 300 μm are possible, facilitating 'tactile exploration' of the actuated shapes.
