Abstract

SEGUN EL PRINCIPIO DEL DIELECTRICO SOLIDO QUE POSEE POLARIZACION ELECTRICA PERSISTENTE (ELECTRETO)Y ONDA DE COMPRENSION, SE FABRICA UN TRANSDUCTOR QUE COMPRENDE UNA CARCASA HUECA EN LA QUE SE MONTAN UN DIAFRAGMA TENSADO Y SOPORTE, UN SEPARADOR, PLACA POSTERIOR ELECTRETO Y APARATO ADECUADO PARA PROCESAMIENTO DE SEÑAL ELECTRICA A FIN DE PRESENTAR UN TRANSDUCTOR IMPERMEABLE A LAS CONDICIONES AMBIENTALES EXTRAÑAS, UTILIZANDO UNA HOJA PLANA DE MATERIAL RECUBIERTA POR MEDIO DE LA DEPOSICION DE UN RESISTENTE AL GRABADO DE ACIDO EN LADOS OPUESTOS DE LA HOJA, GRABANDO EQUIDISTANTEMENTE A TRAVES DEL GROSOR DEL MATERIAL.
