This sensitive surface comprises two films ( 2, 4 ) facing each other and means for keeping these two films a certain distance apart when no pressure is exerted on the surface. Each film ( 2, 4 ) has, on its face turned toward the other film: an array of conducting tracks ( 6, 8 ) that do not touch one another, each having a low resistance; a resistive band ( 12, 16 ); and resistive elements ( 10, 14 ), each resistive element connecting a conducting track to the resistive band. To measure the pressure level exerted on this sensitive surface, the resistance equivalent to the resistance of the resistive elements lying in series and in parallel, after at least two conducting tracks have been brought into contact with each other, is measured.
