摘要： Embodiments of the invention include an active fiber with a piezoelectric layer that has a crystallization temperature that is greater than a melt or draw temperature of the fiber and methods of forming such active fibers. According to an embodiment, a first electrode is formed over an outer surface of a fiber. Embodiments may then include depositing a first amorphous piezoelectric layer over the first electrode. Thereafter, the first amorphous piezoelectric layer may be crystallized with a pulsed laser annealing process to form a first crystallized piezoelectric layer. In an embodiment, the pulsed laser annealing process may include exposing the first amorphous piezoelectric layer to radiation from an excimer laser with an energy density between approximately 10 and 100 mJ/cm2 and pulse width between approximately 10 and 50 nanoseconds. Embodiments may also include forming a second electrode over an outer surface of the crystallized piezoelectric layer.

摘要： A piezoelectric body that is excellent in endurance, flexibility and bendability is achieved. A piezoelectric member includes: belt type first and second conductive rubber sheets that face each other; and a piezoelectric layer formed between an upper surface of the first conductive rubber sheet and a lower surface of the second conductive rubber sheet. The piezoelectric layer is made of a piezoelectric coating material with which at least either one of the upper surface of the first conductive rubber sheet and the lower surface of the second conductive rubber sheet is coated. When a pressure is applied to the piezoelectric layer through at least either one of the first conductive rubber sheet and the second conductive rubber sheet, a potential difference is generated between the first conductive rubber sheet and the second conductive rubber sheet.

摘要： Piezoelectric transducer for the production of, for example, hydrophones, with the transducer including a plurality of sensitive coaxial elements interconnected so as to compensate for the effects of accelerations and deflections.A transducer includes at least one pair of sensitive elements composed of sections of radially polarized coaxial piezoelectric cables having an opposing orientation, with an external armouring of one being connected with an internal armouring of the other, and vice versa. By increasing the number of parts of sensitive elements and selecting the relative disposition, it is possible to improve the immunity of the transducer to noise due to accelerations and deflections, regardless of the direction or the need to license a direction where the transducer is sensitive to such noise. A predetermined number of pairs of sensitive elements can be combined around a central column for accommodating connectors or cables.To be applied, for example, to the production of hydrophones.
