摘要： The present invention relates to a multilayer piezoelectric transformer (Fig.1) that uses a composite resonant vibration mode for step-up voltage conversion. More specifically, a multilayer piezoelectric transformer (fig.1) is provided using radial and shear vibration modes for step-up voltage conversion applications. Adjacent layers of piezoelectric acts as a constraint (40) on the deformation of one face (40a) of the input layers, (40); leading to a gradient in the radial deformation of both the input (2A) and output portions. (2B) ,the piezoelectric transformer ( fig.1) is used in a circuit (fig.11) for providing electro-luminescent ( 200) (EL) backlighting.

摘要： The present invention relates to electroactive polymers (152) that are pre-strained to improve conversion from electrical to mechanical energy. When a voltage is applied to electrodes (156) contacting a pre-strained polymer (152), the polymer (152) deflects. This deflection may be used to do mechanical work. The pre-strain improves the mechanical response of an electroactive polymer (152). 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 fabrication electromechanical devices including one or more electroactive polymers.

摘要： A method is provided by which filters consisting of a plurality of think film bulk acoustic resonators (FBAR) fabricated on a semiconductor wafer such as silicon or some other type of wafer can be hermetically packaged in a way that presents a component which can be easily handled by conventional pick-and-place machines. This package consists of a sandwich of the wafer (1) bearing the thin film piezoelectric resonator (2) and at least one silicon wafer (8, 14). The bond between these wafers (1, 8, 14) is accomplished by some means such as anodic bonding, using a low melting point glass or a metal bonding layer. Contacts to the resonating components are accomplished by etching holes (12) through one of the bonded wafers (8) using a process such as deep reactive ion etching. Contact electrodes are deposited into the holes (12) and onto the surface of the wafer bearing the holes (12). The resulting chip components are separated prior to use by sawing or some other method. As an alternative etching, contact electrodes can be deposited onto the edges of the chips after separation (Figure 9).
