    摘要: There is disclosed a piezoelectric/electrostrictive device made of piezoelectric/electrostrictive film which includes: a substrate section; and an operation section disposed on the substrate section and constituted of a piezoelectric/electrostrictive film and an electrode film and which operates by displacement of the operation section. The operation section comprises the piezoelectric/electrostrictive films and electrode films alternately laminated so that uppermost and lowermost layers form the electrode films, the operation and substrate sections are integrally fired, and the substrate section is constituted of a ceramic which contains a titanium element. For the piezoelectric/electrostrictive device made of piezoelectric/electrostrictive film, a residual stress after firing hardly exists, therefore larger displacement is obtained with the same driving voltage, response speed is higher, and generation force is larger.

    摘要: A matrix type piezoelectric/electrostrictive (P/E) actuator includes a plurality of piezoelectric/electrostrictive elements, each including a piezoelectric/electrostrictive body and at least one pair of electrodes formed on a ceramic substrate. The matrix type P/E actuator is activated by the displacement of the piezoelectric/electrostrictive bodies. The piezoelectric/electrostrictive elements are joined to the ceramic substrate as respective unified bodies, and are two-dimensionally arranged independently from each other. The piezoelectric/electrostrictive actuator provides a greater displacement with a lower voltage, a high responsive speed, and a greater generating force, as well as enhancing the mounting ability and the integration. A method for manufacturing such a matrix type P/E actuator is also disclosed.
