摘要： This invention pertains to piezoelectric actuators made of single crystal active elements which not only exhibit uniform and superior displacement in the axial direction but also of lower cost to produce than full single crystal ring or tube actuators. Said multi-stake actuator is made up of multiple longitudinal (d33) or transverse (d3i or d32) mode piezoelectric single crystal active elements, bonded together by epoxy with the aid of shaped edge- and top and bottom washer-stiffeners which are configured to suit various application needs.

摘要： A compliant suspension element is disclosed for use in mounting an electronic touch screen or touch surface. At least one compliant suspension element couples a touch screen and a housing component together such that the touch screen component is movable relative to the housing component. A segment of piezo material is coupled to opposing surfaces of the at least one suspension element for producing a force that moves the touch screen component relative to the housing component and thereby provide a haptic effect to a user of the touch screen component. In reaction to the force produced by the segments of piezo material, the at least one suspension element is configured to allow movement of the touch screen component relative to the housing component in a first direction and to limit movement between the touch screen component and the housing component in at least a second direction.

摘要： A process for producing a patterned deformable polymer film for use in a deformable polymer device is disclosed. The process includes positioning an intermediary layer between a deformable film and a process tooling and printing at least one electrode on the deformable film by depositing an. ink to form the at least one electrode on a first surface of the deformable film, wherein the intermediary layer permits release of the deformable film from the process tooling subsequent to the printing process. Films produced by the inventive processes may find use in electroactive polymer devices.

摘要： This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for making and using accelerometers. Some such accelerometers include a substrate, a first plurality of electrodes, a second plurality of electrodes, a first anchor attached to the substrate, a frame and a proof mass. The substrate may extend substantially in a first plane. The proof mass may be attached to the frame, may extend substantially in a second plane and may be substantially constrained for motion along first and second axes. The frame may be attached to the first anchor, may extend substantially in a second plane and may be substantially constrained for motion along the second axis. A lateral movement of the proof mass in response to an applied lateral acceleration along the first or second axes may result in a change in capacitance at the first or second plurality of electrodes.
