  • Sensor detector element for an electrical hygrometer
    Patent number: 4347550
    Abstract: A strictly capacitive sensor for an electrical hygrometer comprises an electrode in the form of a slice of doped silicon supporting a dielectric layer of hygroscopic material which in turn supports a further and permeable electrode, while the surface of the silicon which supports the dielectric layer is oxidized to provide an impermeable barrier layer which prevents the sensor acting resistively.
