A brief history of bioelectrodes.

The history of bioelectrodes is intimately associated with electrochemistry in general, through studies on electrode polarization. Electrode polarization was first recognized and studied in the early 1800s, and scientific studies in this area have continued since that time. Experimental and theoretical work on bioelectrodes, electrode polarization, and relevant electrochemistry of electrode phenomena, is traced from 1826 to Schwan's recent electrode work.
