Abstract (en)
[origin: EP0358587A1] The present invention relates to a system for the detection of pressure on a face, consisting of a deformable rubber element containing carbon (5) which comes into mechanical contact with conductors (3) placed on an insulator (2), causing the electrical resistance between the conductors (3) to fall from infinity to a few thousand Ohms. Applications to the detection of the passage of vehicles or pedestrians. <IMAGE>
