  • Patent number: 9553254
    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.

  • Publication number: 20140197936
    Abstract: An actuator module is disclosed. The actuator module includes an actuator having at least one elastomeric dielectric film disposed between first and second electrodes. A suspension system having at least one flexure is coupled to the actuator. The flexure enables the suspension system to move in a predetermined direction when the first and second electrodes are energized. A mobile device that includes the actuator module and a flexure where the actuator module assembly is used to provide haptic feedback also are disclosed.

  • Patent number: 8093783
    Abstract: The invention describes rolled electroactive polymer devices. The invention also describes employment of these devices in a wide array of applications and methods for their fabrication. A rolled electroactive polymer device converts between electrical and mechanical energy; and includes a rolled electroactive polymer and at least two electrodes to provide the mechanical/electrical energy conversion. Prestrain is typically applied to the polymer. In one embodiment, a rolled electroactive polymer device employs a mechanism, such as a spring, that provides a force to prestrain the polymer. Since prestrain improves mechanical/electrical energy conversion for many electroactive polymers, the mechanism thus improves performance of the rolled electroactive polymer device.

  • Patent number: 7703742
    Abstract: The invention describes devices for controlling fluid flow, such as valves. The devices may include one or more electroactive polymer transducers with an electroactive polymer that deflects in response to an application of an electric field. The electroactive polymer may be in contact with a fluid where the deflection of the electroactive polymer may be used to change a characteristic of the fluid. Some of the characteristic of the fluid that may be changed include but are not limited to 1) a flow rate, 2) a flow direction, 3) a flow vorticity, 4) a flow momentum, 5) a flow mixing rate, 6) a flow turbulence rate, 7) a flow energy, 8) a flow thermodynamic property. The electroactive polymer may be a portion of a surface of a structure that is immersed in an external fluid flow, such as the surface of an airplane wing or the electroactive polymer may be a portion of a surface of a structure used in an internal flow, such as a bounding surface of a fluid conduit.

  • Publication number: 20090184606
    Abstract: The invention describes electroactive polymer devices in both rolled and unrolled configurations. The invention also describes employment of these devices in a wide array of applications and methods for their fabrication. An electroactive polymer device converts between electrical and mechanical energy; and, in one embodiment includes a rolled electroactive polymer and one or more electrodes to provide the mechanical/electrical energy conversion. In one embodiment, the electroactive polymer has a non-uniform surface on which an electrode having a non-uniform shape is disposed.
