Patent ID: 7216417

Claim:
Method for manufacturing an electromechanical sensor clement for converting mechanical forces produced by the movements and vital functions of a person into electric signals, in which method a sensor film ( 11 ) is provided with film-like metallic electrodes ( 15 , 16 ) on either side of it and a film-like insulating material ( 12 – 14 ) is fitted on the outer surface of at least one of said metallic electrodes in which method the sensor element is produced by cutting it off a larger amount of sensor element material, characterized in that in the manufacture of the sensor element material, the electrodes arc created by printing an insulation pattern on the metal film on the surface of the insulator film ( 12 – 14 ) in a continuous roll-to-roll process ( 31 , 32 ) and removing the metallic material from areas outside the pattern by etching as a continuous roll-to-roll process, and that the patterned film and the sensor film are laminated together as a continuous rod-to-roll process, wherein the sensor film is provided with earth electrodes placed against it on either side, at least one of said earth electrodes being provided with holes, and that a film containing signal electrodes is placed on the next film layer in the area of the holes.
