Self-charging of medical instruments based on bioelectric potentials

Today, the designers of medical instruments seek to find more compact standalone recharging systems for the low power medical devices in order that it can be used in isolated and remote communities where electricity is unavailable. In the present study, we will try to show that the electrical activity of the human body can be considered as a source of electrical energy and it can recharge chemical storage batteries. Thus, we have used a recharging a discharged nickel metal hydride battery to accumulate energy based on bioelectric potentials. Promising results have been obtained with a configuration of the offset potentials greater than 10mV.
