ABSTRACT:
Composites for actuating or sensing deformation. In embodiments, the composites have a series of flexible, elongated piezoelectric fibers arranged in a parallel array with adjacent fibers separated by relatively soft polymer. The piezoelectric fibers have a common poling direction transverse to their axial extension. The composite further includes flexible conductive material along the axial extension of the fibers for imposing or detecting an electric field.
