A prosthesis system includes a liner made of an electrically non-conducting liner material, which is intended to be pulled over an amputation stump, at least one electrode, which has at least one contact surface, and a prosthesis socket, which is intended to be arranged on the amputation stump. The at least one electrode is arranged on the inner face of the prosthesis socket, at least one area of the liner has a multiplicity of lead-throughs from the inner face to the outer face made of an electrically conducting material arranged in the liner material, and the at least one contact surface of the at least one electrode is intended to come into contact with at least one lead-through during use.
