Abstract
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.
