Claims22
An electroactive polymer device comprising:
- at least one layer of a dielectric, electroactive polymer comprising a polymerized product of at least one ethylenically unsaturated nitrogen-containing monomer with the proviso that the ethylenically unsaturated nitrogen-containing monomer is not acrylonitrile, wherein the electroactive polymer device is selected from a piezoelectric device, pyroelectric device, actuator, transducer, or sensor and wherein the electroactive polymer exhibits a mechanical response to an electric field or produces energy in response to a mechanical stress.
A transducer for converting between electrical energy and mechanical energy, the transducer comprising:
- an actuating component, the actuating component comprising at least one layer of a dielectric polymer comprising a polymerized product of at least one ethylenically unsaturated nitrogen-containing monomer with the proviso that the ethylenically unsaturated nitrogen-containing monomer is not acrylonitrile;
- a first electrode, electrically connected to the actuating component;
- and
- a second electrode, electrically connected to the actuating component,
- wherein upon application of an electric field across the actuating component, the at least one layer of the polymer is mechanically displaced.
