Abstract

EL DISPOSITIVO (11) DE ENTRADA DE DATOS COMPRENDE, SOBRE UNA DISPOSICION (2) DE CAPA RESISTIVA, UNA DISPOSICION (4) DE CAPAS DEFORMABLES QUE SE COMPONEN AL MENOS PARCIALMENTE DE MATERIAL DIELECTRICO. ESTE MATERIAL ES ELASTICAMENTE DEFORMABLE DE MODO QUE, CUANDO LA PRESION SE APLICA SOBRE LA SUPERFICIE DE ENTRADA, LA DISTANCIA ENTRE LA SUPERFICIE DE ENTRADA Y LA DISPOSICION (2) DE CAPA RESISTIVA SE REDUCE EN EL PUNTO DE PRESION. SOBRE EL LADO DE LA DISPOSICION (4) DE CAPA DEFORMABLE QUE SE ENCUENTRA MAS ALLA DE LA DISPOSICION (2) DE CAPA RESISTIVA, ESTA DISPUESTO UN ELECTRODO, EL CUAL ESTA FORMADO PREFERIBLEMENTE COMO UNA CAPA (1) CONDUCTORA. POR ESTO SE PRODUCE UN CAMBIO DE LAS PROPIEDADES CAPACITIVAS DE LA DISPOSICION (4) DE CAPA DEFORMABLE EN EL PUNTO DE PRESION PUESTO QUE EL ESPESOR DE LA DISPOSICION (4) DE CAPA DEFORMABLE SE REDUCE SOBRE ESTE PUNTO. ESTA MEDIDA CAPACITIVA SE USA PARA DETECCION DE LA FUERZA DE PRESION, MIENTRAS QUE LA POSICION DEL PUNTO DE PRESION DENTRO DE LA SUPERFICIEDE ENTRADA SE DETECTA EN DOS DIRECCIONES MUTUAMENTE ORTOGONALES SOBRE LA BASE DEL DIVISOR DE TENSION FORMADO EN LA DISPOSICION (4) DE CAPA RESISTIVA.
