Elastomeric Dielectric Polymer Film Sonic Actuator

View page
US Patent:
6343129, Jan 29, 2002
Filed:
Jul 19, 1999
Appl. No.:
09/356801
Inventors:
Ronald E. Pelrine - Boulder CO
Roy D. Kornbluh - Palo Alto CA
Joseph S. Eckerle - Redwood City CA
Assignee:
SRI International - Menlo Park CA
International Classification:
H04R 2500
US Classification:
381191, 381116, 381174
Abstract:
A sonic actuator including a multi-layer membrane having an elastomeric dielectric polymer layer with a first surface and a second surface, a first compliant electrode layer contacting the first surface of the polymer layer, and a second compliant electrode layer contacting the second surface of the polymer layer. The actuator further includes a support structure in contact with the sonic actuator film. Preferably, the dielectric polymer is selected from the group consisting essentially of silicone, polyurethane fluorosilicone, fluoroelastomer, natural rubber, polybutadiene, nitrile rubber, isoprene, and ethylene propylene diene. Also preferably, the compliant electrode layer is made from the group consisting essentially of graphite, carbon, and conductive polymers. The support structure can take the form of grid having a number of circular apertures. When a voltage is applied to the electrodes, portions of the film held at the aperture of the support structure can bulge due to the electrostriction phenomenon.

Frictionless Transport Apparatus And Method

View page
US Patent:
6361268, Mar 26, 2002
Filed:
Jun 21, 2000
Appl. No.:
09/598825
Inventors:
Ronald E. Pelrine - Boulder CO
Jonathan R. Heim - Pacifica CA
Assignee:
SRI International - Menlo Park CA
International Classification:
B65G 1133
US Classification:
4147492, 104284, 104286
Abstract:
A frictionless transport apparatus for transporting an object from a first to a second station is disclosed. The apparatus has a frame extending between the first and second stations and a carriage mounted for movement along said frame, in a levitated condition. A substantial portion of the weight of the carriage and load is supported by biasing magnets on the frame and carriage. The carriage and load are stabilized in a levitated condition by magnetic interactions between a diamagnetic plate on the carriage and a magnetic array extending along the frame. The carriage is moved in its levitated condition by a frictionless drive system, such as an electromagnetic, electrostatic, or pneumatic drive system. Also disclosed is a method of frictionless transport of an object between first and second stations.

Electroactive Polymer Electrodes

View page
US Patent:
6376971, Apr 23, 2002
Filed:
Jul 20, 2000
Appl. No.:
09/619843
Inventors:
Ronald E. Pelrine - Boulder CO
Roy D. Kornbluh - Palo Alto CA
Qibing Pei - Fremont CA
Jose P. Joseph - Palo Alto CA
Assignee:
SRI International - Menlo Park CA
International Classification:
H01L 41047
US Classification:
310363
Abstract:
The present invention relates to electroactive polymers that are pre-strained to improve conversion from electrical to mechanical energy. When a voltage is applied to electrodes contacting a pre-strained polymer, the polymer deflects. This deflection may be used to do mechanical work. The pre-strain improves the mechanical response of an electroactive polymer. The present invention also relates to actuators including an electroactive polymer and mechanical coupling to convert deflection of the polymer into mechanical work. The present invention further relates to compliant electrodes that conform to the shape of a polymer. The present invention provides methods for fabricating electromechanical devices including one or more electroactive polymers.

Electroactive Polymer Animated Devices

US Patent:
6586859, Jul 1, 2003
Filed:
Apr 4, 2001
Appl. No.:
09/828496
Inventors:
Roy D. Kornbluh - Palo Alto CA
Ronald E. Pelrine - Boulder CO
Paul K. Gallagher - San Jose CA
Joseph S. Eckerle - Redwood City CA
Donald E. Czyzyk - Santa Clara CA
Subramanian Venkat Shastri - Palo Alto CA
Qibing Pei - Fremont CA
Assignee:
SRI International - Menlo Park CA
International Classification:
H02N 100
US Classification:
310309
Abstract:
The present invention relates to animated devices that include one or more electroactive polymer transducers. When actuated by electrical energy, an electroactive polymer produces mechanical deflection in one or more directions. This deflection may be used to produce motion of a feature included in an animated device. Electroactive polymer transducers offer customizable shapes and deflections. Combining different ways to configure and constrain a polymer, different ways to arrange active areas on a single polymer, different animated device designs, and different polymer orientations, permits a broad range of animated devices that use an electroactive polymer transducer to produce motion. These animated devices find use in a wide range of animated device applications.
