Patent ID: 6937893

Claim:
A physically active patch having a planar substrate which is provided on one side with an adhesive layer, and a side remote from the adhesive layer, the side of the substrate remote from the adhesive layer including at least in regions a first electrode and above the first electrode, at least in regions, a layer including at least one of a piezoelectric polymer material, a quasi-piezoelectric polymer material and an electrostrictive polymer material, and above the at least one of a piezoelectric polymer material, a quasi-piezoelectric polymer material and an electrostrictive polymer material, at least in regions, a second electrode, the first electrode and the second electrodes are structured, having a plurality of individual electrode strips lying parallel to one another, the two electrodes being so disposed that a longitudinal direction of the electrode strips of the first electrode is perpendicular to a longitudinal direction of the electrode strips of the second electrode.
