A method for fabricating electroactive polymer transducers, the includes providing an electroactive polymer film comprising an elastomeric dielectric polymer, forming an array of electrodes on the film, and sandwiching the electrode array between a top and bottom array of frame components to form an array of electroactive polymer transducers.

Method of manufacturing electroactive polymer transducers for sensory feedback applications

The present invention provides an optical system comprising a lens element, a display unit displaced transversely from the lens element, at least one actuator coupled to at least one of the lens element or the display unit and capable of changing position of the lens element relative to the display unit in a lateral direction, and an electronic control system capable of driving the at least one actuator to move in a programmed manner to control positioning of the lens element relative to the display unit.

Electroactive polymer actuator lenticular system

The present invention provides optical systems, devices and methods which utilize one or more electroactive films to adjust an optical parameter of the optical device/system.

Optical systems employing compliant electroactive materials

Electroactive polymer transducers for sensory feedback applications are disclosed.

Optical lens displacement systems

Electroactive polymer transducers for sensory feedback applications

The present invention provides optical systems, devices and methods which utilize one or more electroactive polymer actuators to stabilize the image produced by the device or system.

Optical lens image stabilization systems

Electroactive polymer transducers are disclosed. They are biased in a manner that provides for increased force and/or stroke output, thereby offering improved work potential and power output capacity. The biasing may offer additional or alternate functional advantage in terms of matching transducer performance with a given application such as a normally-closed valve. The improved biasing (including increased output biasing) may utilize negative spring rate biasing and/or a combination of negative or zero-rate biasing with positive rate biasing to achieve the desired ends.
