Electrically conductive polymer gel and the method for manufacturing the same and an organism-use electrode with the use thereof

Abstract From the Canadian patent

An electrically conductive polymer gel is composed a crosslinked polyacrylamide polymer including electrolytic salt water and polyhydric alcohol uniformly dissolved therein the water and the polyhydric alcohol being major components of said polymer gel. The polyacrylamide series polymer in the gel has properties of hydrophilic and nonelectrolyte. Therefore a desirable connection between the gel and the electrode can be achieved with low impedance. Moreover the polyhydric alcohol reduces the drying speed of the electrically conductive polymer gel thereby preventing an increase in the impedance due to the dryout of the gel. Therefore the electrically conductive polymer gel of the present …
