Electropoise

The Electropoise is a gas-pipe device, developed and patented by Hercules Sanche, that was marketed as an instrument for oxygen therapy, promising to make the wearer "oxygen positive" through a process described as "thermo-electric induction" (or "Diaduction") that would "polarise" the body, thereby attracting oxygen and enabling absorption through the pores of the skin.
