Claims

1. AN ELECTRODE ASSEMBLY FOR DETECTING LOW LEVEL ELECTRICAL SIGNALS FROM THE SKIN OF A LIVING CREATURE COMPRISING:

A RELATIVELY THIN DISC OF NONCONDUCTING MATERIAL HAVING A FACE FOR CONTACTING A SKIN SURFACE;

SAID DISC HAVING A RIGID WALL RECESSED BEHIND SAID FACE;

SAID DISC HAVING AN ELECTROLYTE RESERVOIR BEHIND SAID WALL;

AN ELECTRODE COMPONENT FIXEDLY MOUNTED IN SAID RESERVOIR AND SPACED BEHIND SAID WALL;

SAID RIGID WALL OF SAID DISC HAVING A PLURALITY OF OPENINGS THERETHROUGH OF SUFFICIENTLY SMALL SIZE SO THAT WHEN SAID WALL CONTACTS A SKIN SURFACE THE MOVEMENT OF THE SKIN OR COMPRESSION THEREOF INTO THE OPENINGS ARE INSUFFICIENT TO MECHANICALLY DISTURB ELECTROLYTE CLOSELY ADJACENT TO SAID ELECTRODE COMPONENT;

AND A CONDUCTOR CONNECTED TO SAID ELECTRODE COMPONENT AND EXTENDING TO THE EXTERIOR OF SAID DISC.
