摘要:
A PZT fiber is formed by using a titanium wire or a heat-resistant metal wire made of platinum or the like, as a core wire, and overlaying PZT crystals on a surface of the wire. A smart board utilizing the PZT fiber is formed by embedding the PZT fiber into a conductive composite material layer made of carbon fiber reinforced plastic or the like. An actuator utilizing the smart board is constituted by applying a voltage between the PZT fiber and the conductive composite layer of the smart board.

摘要:
A piezoelectric sheet, which comprises a matrix comprising a polyimide, silicone rubber or an epoxy resin, and a cubic lead zirconate titanate single-crystal particle dispersed in the matrix, wherein (100) plane of said single-crystal particle is oriented parallel to a plane of said sheet, and said single-crystal particle penetrates the plane of said sheet from one to the other side. Conventionally, since the constituent crystal particles are randomly oriented, properties of the crystal particles are obtained as the average values of the properties of the individual particles. In contrast, according to the piezoelectric sheet of the present invention, since the cubic PZT single-crystal particles have been disposed so that (100) axes are oriented perpendicularly to the plane of the sheet, the PZT can have the properties inherent in the (100) planes.
