摘要: The invention discloses a periodic orthogonal polarized large strain piezoelectric ceramic actuator and making method thereof. A plate is employed comprises n basic domain units, each unit c an which are perpendicular to other; under the action of unidirectional positive electric field, extension amount switching caused by non 180 DEG substantially greater than adjacent effect, so mismatching stress generated because at interface domain, domains two sides in pulled state; when field removed, actuating returns zero, restorable realized. advantaged that solution scheme utilizing industrial ceramics generate super provided, process simple, cost low, suitable for batch production, farther higher routine actuator, can realize wide application.
