Abstract

SENSOR DE HUMEDAD CAPACITIVO QUE COMPRENDE UN SUSTRATO, UNA CAPA INFERIOR CONDUCTORA IMPERMEABLE A LA HUMEDAD COMO PRIMERA PLACA CAPACITORA, UNA CAPA DIELECTRICA Y UNA CAPA SUPERIOR CONDUCTORA PERMEABLE A LA HUMEDAD COMO SEGUNDA PLACA CAPACITORA, Y ALAMBRES DE CONEXION ASOCIADOS CON LAS PLACAS CAPACITORAS PRIMERA Y SEGUNDA, POR LOS QUE SE MIDE EL CAMBIO EN LA CONSTANTE DIELECTRICA, Y POR LO TANTO EN EL VALOR DE CAPACITANCIA, DEBIDO A LA ABSORCION DE MOLECULAS DE AGUA. EL SUSTRATO ES UN LAMINADO DE COBRE FLEXIBLE EN EL QUE ESTA GRABADO POR LO MENOS LA CAPA INFERIOR CONDUCTORA, Y LA CAPA SUPERIOR CONDUCTORA COMPRENDE UNA CAPA IMPRESA SOLIDA CON UN ESQUEMA DE REJILLA CONDUCTORA, QUE ESTA IMPRESA CON TINTA CONDUCTORA.
