Patent ID: 6996891

Claim:
Method for manufacturing an electromechanical sensor element, in which method both surfaces of a sensor film are fitted with metallic electrode films and the outer surface of at least one of the metallic electrode films is fitted with a dielectric film, said sensor element being produced by cutting the sensor element from a larger amount of sensor element material, characterized in that, in the manufacture of the sensor element material, at least one of the electrodes is created by printing a dielectric pattern corresponding to the electrode onto a surface of a metal film on the surface of the dielectric film in a continuous processes from roll to roll and removing the metal from the areas outside the pattern by etching in a continuous process from roll to roll, and wherein the patterned film and the sensor film are laminated together in a continuous process from roll to roll, and wherein at least one of the metallic electrode films comprises repeated electrode patterning.
