Abstract

The present invention provides a piezoelectric element of fiber or fabric form , from which electrical output can be drawn through relatively low stress produced by rubbing the surface with the fingers or the like. The present invention is a piezoelectric element including piezoelectric units that include two conductive fibers and one piezoelectric fiber the fibers having points of mutual contact , while being arranged generally on the same plane.
