Abstract
A device for detecting the amount or concentration of particulate matter in a gas medium comprises a structure for the deposit of solid particles, at least a first and a second electrode associated to the structure, and means for measuring an electric quantity between the first and second electrode. A plurality of cavities is defined in the structure, which act as collectors of solid particles, the structure being arranged so as to induce the accumulation of the particles inside the cavities.
