Abstract: The present invention provides electroactive polymer (“EAP”) transducers having improved properties. This improvement is achieved without decreasing film thickness, or by using high dielectric constant and high field, so that this approach does not adversely affect the reliability and physical properties of the resultant dielectric films. Mobile electrically active additives are added to the electrode formulation which significantly improve the performance of electroactive polymer transducers. Such additives do not need to be ionic. These electrically active additives can enable higher performance devices, smaller devices using less active area, lower voltage/power operation, and combinations of these enhancements.

Abstract: The present invention provides a housing to allow for removable coupling of electroactive polymer transducer with an electronic media device, where the housing produces an improved haptic effect in the electronic media device.

The present process may be employed for producing improved monolithic actuator elements such as configurable buttons, arrays of buttons, and the like.

Abstract: A process for producing a patterned deformable polymer film for use in a deformable polymer device is disclosed. The process includes positioning an intermediary layer between a deformable film and a process tooling and printing at least one electrode on the deformable film by depositing an ink to form the at least one electrode on a first surface of the deformable film, wherein the intermediary layer permits release of the deformable film from the process tooling subsequent to the printing process. Films produced by the inventive processes may find use in electroactive polymer devices.
