Abstract
A sensor of volatile substances includes: a first electrode structure and a second electrode structure capacitively coupled, comb-fingered, and arranged coplanar in a plane; and a sensitive layer, of a sensitive material that is permeable to a volatile substance and has electrical permittivity depending upon a concentration of the volatile substance absorbed by the sensitive material. The sensitive layer extends from opposite sides of the plane.
