  • Patent number: 8429808
    Abstract: A method for fabricating electrostatic transducers and arrays electrically separates the substrate segments of the transducer elements from each other using a technique involving two cutting steps, in which the first step forms a patterned opening in the substrate to make a partial separation of substrate segments, and the second step completes the separation after the substrate segments have been secured to prevent instability of the substrate segments upon completion of the second step. The securing of the substrate segments may be accomplished by filling a nonconductive material in the partial separation or securing the transducer array on a support substrate. When the substrate is conductive, the separated substrate segments serve as separate bottom electrodes that can be individually addressed. The method is especially useful for fabricating ID transducer arrays.

  • Patent number: 8261428
    Abstract: The present invention discloses a method for assembling a 3D microelectrode structure. Firstly, 2D microelectrode arrays are stacked to form a 3D microelectrode array via an auxiliary tool. Then, the 3D microelectrode array is assembled to a carrier chip to form a 3D microelectrode structure. The present invention uses an identical auxiliary tool to assemble various types of 2D microelectrode arrays having different shapes of probes to the same carrier chip. Therefore, the method of the present invention increases the design flexibility of probes. The present invention also discloses a 3D microelectrode structure, which is fabricated according to the method of the present invention and used to perform 3D measurement of biological tissues.

  • Patent number: 8234774
    Abstract: One embodiment of the present invention sets forth a method for decreasing a temperature coefficient of frequency (TCF) of a MEMS resonator. The method comprises lithographically defining slots in the MEMS resonator beams and filling the slots with oxide. By growing oxide within the slots, the amount of oxide growth on the outside surfaces of the MEMS resonator may be reduced. Furthermore, by situating the slots in the areas of large flexural stresses, the contribution of the embedded oxide to the overall TCF of the MEMS resonator is increased, and the total amount of oxide needed to decrease the overall TCF of the MEMS resonator to a particular target value is reduced. As a result, the TCF of the MEMS resonator may be reduced in a manner that is more effective relative to prior art approaches.

    Abstract: An actuator includes a sheet having dielectric elastomer layers and conductive rubber layers provided on the front and back faces of each dielectric elastomer layer. The sheet is wrapped and rolled about a coil spring. The actuator expands the rolled sheet along an expansion direction of the coil spring by applying a voltage to the conductive rubber layers on the front and back faces of the dielectric elastomer layer, and contracts the rolled sheet along a contraction direction of the coil spring by stopping the application of the voltage. The actuator further includes a fiber layer located between the coil spring and the rolled sheet wrapped about the coil spring.

  • Publication number: 20110278993
    Abstract: A piezoelectric device is manufactured in which the material of a supporting substrate can be selected from various alternative materials. Ions are implanted into a piezoelectric substrate to form an ion-implanted portion. A temporary supporting substrate is formed on the ion-implanted surface of the piezoelectric substrate. The temporary supporting substrate includes a layer to be etched and a temporary substrate. The piezoelectric substrate is then heated to be divided at the ion-implanted portion to form a piezoelectric thin film. A supporting substrate is then formed on the piezoelectric thin film. The supporting substrate includes a dielectric film and a base substrate. The temporary supporting substrate is made of a material that produces a thermal stress at the interface between the temporary supporting substrate and the piezoelectric thin film less than the thermal stress at the interface between the supporting substrate and the piezoelectric thin film.
