Abstract:
A capacitive sensor for detecting the presence of a substance includes a plurality of upstanding conductive pillars arranged within a first layer of the sensor, a first electrode connected to a first group of the pillars, a second electrode connected to a second, different group of the pillars, and a dielectric material arranged adjacent the pillars, for altering the capacitance of the sensor in response to the presence of said substance.
