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...http://www.google.fr/patents/US5869189?utm_source=gb-gplus-shareBrevet US5869189 - Composites for structural control
