Abstract

LOS PIEZOACCIONADORES DE MULTIPLES CAPAS SE FABRICAN APILANDO Y PRESIONANDO CAPAS ALTERNAS DE MATERIAL DE PIEZOCERAMICA Y MATERIAL DE ELECTRODOS. EL MATERIAL DE ELECTRODOS SE PROPORCIONA CON POROS O AGUJEROS DISTRIBUIDOS EN EL. DURANTE EL PRESIONADO, EL MATERIAL DE CAPAS PIEZOCERAMICAS FLUYE Y LLENA LOS AGUJEROS DE LOS ELECTRODOS, IMPARTIENDO ASI AL BLOQUE UNA ESTRUCTURA MONOLITICA.
