Patent number: 6879162Abstract: Described are a method and system for dispensing a fluid. A fluid-dispensing device includes a substrate and a plurality of nozzles formed in the substrate. Each nozzle has an open-ended tip and a fluid-conducting channel between the tip and a source of fluid. A non-conducting spacer is on the substrate and electrically isolates a gate electrode from the substrate. The gate electrode is located adjacent to the tip of at least one of the nozzles to effect dispensing of the fluid in that nozzle in response to a voltage applied between the gate electrode and the nozzle or fluid in the nozzle. In one embodiment, the gate electrode includes a plurality of individually addressable gate electrodes used for selectively actuating nozzles.Type: GrantFiled: October 31, 2002Date of Patent: April 12, 2005Assignee: SRI InternationalInventors: Victor M.

Patent number: 6583533Abstract: 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.Type: GrantFiled: November 15, 2001Date of Patent: June 24, 2003Assignee: SRI InternationalInventors: Ronald E.
