摘要： 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.

After a damaged layer formed on a surface of the piezoelectric substrate is removed, an under-electrode layer including at least one of Ti and Cr as a main component is formed by a vacuum deposition process at a temperature of about 100° C. or less, and an Al electrode layer including Al or an Al main component is then formed on the under-electrode layer. The Al electrode layer has a twin crystal structure in which the Al crystal is oriented in a desired direction such that the (111) crystal plane of Al substantially coincides with the Z crystal direction of the piezoelectric substrate.

摘要： A method of bonding a piezoelectric element and an electrode, including the steps of forming a first coating of a material selected from the group consisting of Au, Al, Zn, Cu, and Sn on a bonding surface of the piezoelectric element, and forming a second coating of a material selected from the group consisting of Au, Al, Zn, Cu, and Sn on a bonding surface of the electrode. The combination of the materials of the first and second coatings is preferably Au/Au, Au/Al, Zn/Cu, or Sn/Cu. The method further includes the step of bringing the first and second coatings into close contact with each other and heating them under pressure to form a metallic bond or intermetallic compound between the first and second coatings, thereby bonding the piezoelectric element and the electrode.

摘要： A piezoelectric transducer apparatus comprises at least one piezoelectric unit and a body structure. Each of the at least one piezoelectric unit has a piezoelectric block and at least one pair of electrodes. Each electrode is adhered to one surface of the piezoelectric block. Each of the at least one piezoelectric unit is adhered to the surface of the body structure with the electrode exposed externally. The transducer apparatus has a generalized sensor equation which can be modeled in a fourth-order partial differential equation mathematical system. At least one of the electrodes or the piezoelectric block of each of the at least one piezoelectric unit has a shape matched to a desired body strain pattern existing in the body structure wherein the electrode of each of the at least one piezoelectric unit may excite a strain pattern in the body structure that is the same as the desired body strain pattern. The body structure of any structural configuration may have a resolved electrode shape that results in the disengagement of the phase and gain characteristics of the piezoelectric construction based on that particular body structure.
