Abstract
Abstract An electrotherapeutical device, comprising an electrically insulating substrate, a semiconductor element having photoelectromotive force and thermoelectromotive force and which is adhered to the substrate, and lead wires, one end of each lead wire being connected to the semiconductor element and the other end thereof being formed into a terminal, has a very small size, can be easily arranged on a desired portion of a human body, and can produce a therapeutical effect.

Claim 1
Independent Claim
195 words
An electrotherapeutical device having high therapeutical effect, comprising a substrate in the form of a small sheet of electrically insulating material having a first surface adapted to be placed upon the human body and an opposed second surface; a semiconductor element having both photoelectromotive force and thermoelectromotive force which is in the form of a sheet which is smaller than said sheet of electrically insulating material and which is adhered to said second surface of the substrate; and a pair of lead wires, one end of each lead wire being connected to the semiconductor element and the other end thereof being formed into a terminal so as to be in contact with a human body, the lead wires being connected to the semiconductor element at opposite ends of the semiconductor element, the two terminals of the lead wires being spaced apart so as to contact a human body at two spaced points, and needles connected to the terminals of the respective lead wires, whereby heat from said human body, conducted through said electrically insulating material to said semiconductor element, generates an electrical current that is applied through said wires and needles to said human body.
