ABSTRACT:
A chadd disposed on a patient's skin generates heat at a substantially constant temperature for an extended period of time (e.g., hours and days) when exposed to air. The chadd becomes porous when heated and produces a porosity in the patient's skin as a result of the heat generation to pass ions through the pores in patient's skin to a layer disposed on the chadd. The layer (e.g., silver or silver chloride) has properties of converting the ions to electrons. The electrons pass to an electrical lead disposed on the layer. The electrical lead passes an electrical signal (produced from the electrons) to a terminal. An amplifier connected to the terminal amplifies the signal without changing the characteristics of the signal and without producing noise.
