Abstract

Sensor (1) for measuring at least one physical quantity, which comprises at least one capacitive cell (2) which, in use, varies a related electrical parameter as a function of the physical quantity; the capacitive cell (2) comprising at least a first layer (3) of dielectric or insulating compressible elastic material having at opposite sides a first and a second outer contact surface (3a), and at least a first plate (4) made with a film of paint or ink in compressible and electrically conductive elastic material, which is deposited directly onto the first contact surface (3a) of the first layer (3).
