Patent number: 8665578Abstract: Described herein is electroadhesion technology that permits controllable adherence between two objects. Electroadhesion uses electrostatic forces of attraction produced by an electrostatic adhesion voltage, which is applied using electrodes in an electroadhesive device. The electrostatic adhesion voltage produces an electric field and electrostatic adherence forces. When the electroadhesive device and electrodes are positioned near a surface of an object such as a vertical wall, the electrostatic adherence forces hold the electroadhesive device in position relative to the surface and object. This can be used to increase traction or maintain the position of the electroadhesive device relative to a surface. Electric control of the electrostatic adhesion voltage permits the adhesion to be controllably and readily turned on and off.Type: GrantFiled: January 19, 2012Date of Patent: March 4, 2014Assignee: SRI InternationalInventors: Ronald E. Pelrine, Harsha Prahlad, Joseph S. Eckerle, Roy D. Kornbluh, Scott E. Stanford

Patent number: 8436508Abstract: The present invention provides meta-materials with an actively controllable mechanical property. The meta-material includes a deformable structure and a set of activation elements. The activation elements are controllable between multiple states. The meta-material includes a first value for a mechanical property when one or more of the activation elements is in the first activation state and includes a second value for the mechanical property when the activation elements have been activated to the second activation state. In one aspect, the meta-material resembles a composite material where the connectivity between the component materials or shape and arrangement of the component materials is dynamically controllable so as to affect a mechanical property of the meta-material.Type: GrantFiled: February 29, 2012Date of Patent: May 7, 2013Assignee: SRI InternationalInventors: Roy D. Kornbluh, Ronald E. Pelrine, Harsha Prahlad, Scott E. Stanford

Patent number: 7895985Abstract: Combustion devices described herein comprise a compliant combustion chamber wall or segment. The compliant segment deforms during combustion in the combustion chamber. Some devices may include a compliant wall configured to stretch responsive to pressure generated by combustion of a fuel in the combustion chamber. A coupling portion translates deformation of the compliant segment or wall into mechanical output. One or more ports are configured to inlet an oxygen source and fuel into the combustion chamber and to outlet exhaust gases from the combustion chamber.Type: GrantFiled: December 30, 2008Date of Patent: March 1, 2011Assignee: SRI InternationalInventors: Ronald E. Pelrine, Scott E. Stanford, Harsha Prahlad, Seajin Oh, Jonathan Heim, Roy D. Kornbluh

Patent number: 7804227Abstract: Described herein are several solutions that increase transducer lifetime by reducing or preventing tear propagation in a compliant electroactive polymer. One solution couples a compliant tear resistant treatment to a transducer proximate to an edge portion of the electroactive polymer. Another solution uses a tear resistant layer that couples to and covers a large surface area of the transducer. Another suitable tear resistant solution provides added material outside an active area; the added material reduces stress or strain variations in polymer material outside the active area when the electroactive polymer transducer is deflected or pre-strained.Type: GrantFiled: March 13, 2008Date of Patent: September 28, 2010Assignee: SRI InternationalInventors: Ronald E.
