  • Apparatus and methods for providing tactile stimulus incorporating tri-layer actuators
    Patent number: 10229564
    Abstract: An apparatus provides tactile stimulus to a human user using a tri-layer actuator comprising: first and second polymer layers which are electronically and ionically conductive and have one or more dimensions which vary in dependence on insertion of ions therein and withdrawal of ions therefrom; and a deformable layer located between the first and second polymer layers to physically separate the first and second polymer layers from one another, the deformable layer electronically insulating and ionically conductive. Application of first and second voltages between the first and second polymer layers creates corresponding first and second distributions of ions within the first and second polymer layers. Changing between application of the first and second voltages causes corresponding deformation of the tri-layer actuator between corresponding first and second shapes, a difference or transition between the first and second shapes detectable by a sense of touch of a human user.
