Abstract
LA PRESENTE INVENCION SE REFIERE A UN TACTOR (1) MONOLITICO DE MULTIPLES CAPAS COMPUESTO POR UNA PILA (2) SINTERIZADA DE LAMINAS DELGADAS DE CERAMICA PIEZOELECTRICA, EN LAS QUE HAY INSERTADOS ELECTRODOS INTERNOS (3) METALICOS QUE PUEDEN EXTRAERSE ALTERNATIVAMENTE DE LA PILA (2) Y PUEDEN CONMUTARSE ELECTRICAMENTE DE FORMA PARALELA A TRAVES DE LOS ELECTRODOS EXTERNOS, CARACTERIZADO PORQUE LOS ELECTRODOS EXTERNOS DE LOS LADOS DE CONTACTO DE LA PILA (2) CONSTAN DE UNA BASE DE METAL (4) Y ESTAN UNIDOS CON LOS ELEMENTOS DE CONEXION ELECTRICA (5) PREFERIBLEMENTE A TRAVES DE UNA SOLDADURA. PARA EVITAR QUE SE PRODUZCAN FALLOS EN EL TACTOR DURANTE LAS CARGAS DINAMICAS, SE PROPONE QUE ENTRE LA BASE DE METAL (4) Y LOS ELEMENTOS DE CONEXION (5) SE DISPONGA UN ELECTRODO (6) CONDUCTOR DE LA ELECTRICIDAD CON UNA ESTRUCTURA TRIDIMENSIONAL, EL CUAL DEBE UNIRSE CON LA BASE DE METAL A TRAVES DE PUNTOS DE CONTACTO (7) PARCIALES Y ESTA REALIZADO EN POSICION GIRATORIA ENTRE LOS PUNTOS DE CONTACTO (7).
