Abstract
A skin treatment device includes a substrate and a plurality of discrete galvanic couples provided on the substrate, each discrete galvanic couple including a first conductive electrode that is an anode and a second conductive electrode that is a cathode, wherein the anode of each galvanic couple includes a first metal and the cathode of each discrete galvanic couple includes a second metal, different from the first metal, the first and second metal having a different standard potential.

A skin treatment device comprising a substrate and a plurality of discrete galvanic couples provided on said substrate, each discrete galvanic couple comprising a first conductive electrode that is an anode and a second conductive electrode that is a cathode, wherein the anode of each galvanic couple comprises a first metal and the cathode of each discrete galvanic couple comprises a second metal, different from the first metal, the first and second metal having a different standard potential, wherein, at least one discrete galvanic couple comprises an anode that consists of an assembly of a bottom layer in contact with said substrate and a top layer, the top layer made of a first material comprising said first metal and said bottom layer made of a second material comprising said second metal, the top layer fully covering the bottom layer and in contact with the bottom layer, and the at least one discrete galvanic couple comprises a cathode that consists of a layer in contact with the substrate and made of said second material, the first and second metal of said at least one discrete galvanic couple being selected to allow a generation of a current from 70 to 100 μA between said anode and said cathode.
A method for producing a skin treatment device comprising:
- providing a substrate,
- providing a plurality of discrete galvanic couples on said substrate, each discrete galvanic couple comprising a first conductive electrode that is an anode and a second conductive electrode that is a cathode, wherein the anode of each discrete galvanic couple comprises a first metal and the cathode of each discrete galvanic couple comprises a second metal, different from the first metal, the first and second metal having a different standard potential, wherein providing a plurality of discrete galvanic couples comprises:
- providing a plurality of discrete metal elements on the substrate, said plurality of discrete metal elements comprising a layer of said second metal,
- selecting discrete metal elements of the plurality of discrete metal elements, and
- providing a layer of said first metal on selected discrete metal elements, wherein at least one discrete galvanic couple comprises an anode that consists of an assembly of a bottom layer in contact with said substrate and a top layer, the top layer made of a first material comprising said first metal and said bottom layer made of a second material comprising said second metal, the top layer fully covering the bottom layer and in contact with the bottom layer, and the at least one discrete galvanic couple comprises a cathode that consists of a layer in contact with the substrate and made of said second material, the first and second metal of said at least one discrete galvanic couple being selected to allow a generation of a current from 70 to 100 μA between said anode and said cathode.
