摘要： Provided is a multi-layer piezoelectric element capable of achieving a high response speed and an increase in the displacement amount, ensuring sufficient mechanical strength, and suppressing deterioration of characteristics. A multi-layer piezoelectric element includes a stacked body in which piezoelectric layers and internal electrode layers are alternately laminated, and the piezoelectric layers include a polarization domain extending over a plurality of crystal particles. Since the piezoelectric layers include the polarization domain extending over the plurality of crystal particles, the multi-layer piezoelectric element can achieve a high response speed and an increase in the displacement amount, ensure sufficient mechanical strength, and suppress deterioration of characteristics.

摘要： In the manufacture of a laminated piezoelectric/electrostrictive element by lamination of a piezoelectric/electrostrictive film and an electrode film containing either platinum or an alloy composed mainly of platinum and having a thickness of 2.0 μm or less, both or either one of yttrium oxide (Y2O3) and cerium oxide (CeO2) is added to the electrode film or the piezoelectric/electrostrictive film, and the electrode film and the piezoelectric/electrostrictive film are fired simultaneously. This simultaneously achieves a reduced thickness and improved thermal resistance of the electrode film and a reduced change in piezoelectric/electrostrictive properties with time, thereby producing a piezoelectric/electrostrictive element with good initial piezoelectric/electrostrictive properties and with a small change in the piezoelectridelectrostrictive properties with time.

摘要： An ultrasound transducer includes an array of PZT elements mounted on a non-recessed distal surface of a backing block. Between each element and the backing block is a conductive region formed as a portion of a metallic layer sputtered onto the distal surface. Traces on a longitudinally extending circuit board—preferably, a substantially rigid printed circuit board, which may be embedded within the block—connect the conductive region, and thus the PZT element, with any conventional external ultrasound imaging system. A substantially “T” or “inverted-L” shaped electrode is thereby formed for each element, with no need for soldering. At least one longitudinally extending metallic member mounted on a respective lateral surface of the backing block forms a heat sink and a common electrical ground. A thermally and electrically conductive layer, such as of foil, transfers heat from at least one matching layer mounted on the elements to the metallic member.
