Abstract
Abstract A bioelectrode applicable to a body part has a pouch having a solid bottom formed of a sheet of electrically insulating watertight material being solid throughout said bottom, and a top sealed to said bottom and having an aperture remote from that bottom. The pouch defines an enclosed interior wider than that aperture. An electrode is located in the pouch and is spaced from the mentioned aperture. An electrolyte-absorbing pad is located in the pouch between the electrode and the mentioned aperture and extends in the above mentioned closed interior beyond the width of the aperture. Another bioelectrode applicable to a body party has a pouch having a bottom formed of a sheet of electrically insulating watertight material having a hole, and a top sealed to the bottom and having an aperture remote from the bottom. The pouch defines an enclosed interior wider than the latter aperture. An electrode in the pouch is spaced from the mentioned aperture. The hole in the bottom is closed by a watertight seal formed with the aid of a device providing an electric current conducting lead from the electrode to the outside of the pouch. An electrolyte-absorbing pad extends in the above mentioned enclosed interior beyond the width of the aperture, being in contact with the electrode and accessible at the aperture.
