Abstract

LA INVENCION PROPORCIONA UN DISPOSITIVO PARA MEDIR LA CONCENTRACION DE UNA SUSTANCIA QUIMICA EN UN FLUIDO, CARACTERIZADO POR UN SEMICONDUCTOR QUE CONTIENE UNA SUPERFICIE DE MEDICION, CUYA MAGNITUD DE IMPEDANCIA SE ALTERA AL CONTACTAR LA SUPERFICIE CON LA SUSTANCIA QUIMICA Y SE ENCUENTRA DISPUESTO EN UN ALOJAMIENTO EN EL QUE SE DISPONE UN CANAL DE FLUJO PARA EL FLUIDO Y, DONDE LA SUPERFICIE DE MEDICION FORMA PARTE DE LA PARED DEL CANAL Y ESTA SELLADA EN RELACION CON EL ALOJAMIENTO MEDIANTE UN ELEMENTO SELLANTE QUE SE PUEDE LIBERAR, Y CUYO SEMICONDUCTOR ESTA PROVISTO DE CONDUCTORES ELECTRICOS PARA CONDUCIR LAS SEÑALES DE MEDICION. EL ELEMENTO SELLANTE ES, PREFERIBLEMENTE, UN RETEN O.
