Abstract
An actuator device comprises an EAP structure which deforms in response to a drive signal applied to the device, a device output being derived from movement of the EAP structure. A delay arrangement is used such that the mechanical output from the device is not generated for a first range or type of applied drive signals, and said device output is generated for a second range or type of applied drive signals. This device is for example particularly suitable for use in a passive matrix system.
