Electrically conductive polymer gel, method for manufacturing and use of the polymer gel and an organism-use electrode

摘要

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 invention permits an accurate measurement of an electrical phenomenon in the organism for long periods of time.
