    摘要: A piezoelectric/electrostrictive element including a substantially trapezoidal laminate having narrower and wider surfaces lying substantially in parallel to each other and first and second surfaces opposed to each other between the narrower and wider surfaces. The first and second surfaces are inclined at given angles to one of the narrower and wider surfaces. The laminate includes piezoelectric/electrostrictive layers and interposed internal electrodes, the internal electrodes being broken up into a first and a second group, each of the first group internal electrodes lying over one of the second group internal electrodes through one of the piezoelectric/electrostrictive layers. A first external electrode is formed on the first surface of the laminate and is coupled to the first group internal electrodes. A second external electrode is formed on the second surface of the laminate and is coupled to the second group internal electrodes.

    摘要: A force sensor includes: a supporting base having a hollow portion, a flexible plate having at least one detecting element and extending across over the hollow portion, and an operating member suspended over the hollow portion by the flexible plate. Inclined strength is given to the flexible plate so that it becomes stronger from an arbitrary position between the outer periphery of the operating member and the inner periphery of the supporting base toward the outer periphery of the operating member and/or toward the inner periphery of the supporting base. Another force sensor includes: a supporting base having a hollow portion, a flexible plate having at least one detecting element and extending across over the hollow portion, and an operating member suspended over the hollow portion by the flexible plate. A boundary between the flexible plate and the operating member and/or a boundary between the flexible plate and the supporting base have (has) a curvature.

    摘要: An acceleration sensor element including a weight, a support having a hollow part which is disposed around the weight as a center, and a flexible plate having piezoelectric elements including a piezoelectric body sandwiched by at least one set of electrodes and disposed horizontally across the support to suspend the weight at the hollow part of the support. Acceleration applied from the prior is converted into deflection of the flexible plate based on movement of the weight corresponding to the acceleration, and the direction and rate of the acceleration are three-dimensionally detected by electric charges generated in the piezoelectric body corresponding to deflection of the flexible plate. The piezoelectric elements are disposed only at flexible parts of the flexible plate.
