Abstract

The invention relates to a physically active patch having a planar substrate which is provided on one side with an adhesive layer, a first electrode being arranged, at least in regions, on the side of the substrate remote from the adhesive layer, then above said electrode, at least in regions, a layer formed from a piezoelectric, quasi-piezoelectric and/or electro-strictive polymer material, and above same, at least in regions, a second electrode.
