ABSTRACT:
An adsorbing type sensor of the type having electrically conductive adsorbent particles resiliently embedded in a surface and forming an electrical conductive path through the sensor, the resistance of which or in one embodiment current through which varies in response to the presence of an adsorbate medium exposed to the particles and in which the adsorbent particles are of varying sizes interspersed among one another and a method of increasing the sensitivity and range of an adsorbing type sensor by interspersing various sized abutting adsorbent particles.
