I have a few EKG electrodes, the round things that are stuck on the
skin. I have some of both the kind that are used for a resting EKG, and
also the kind used for a stress (treadmill) EKG.
What are these things, electrically? They are soft rubber(?) discs that
are about 1.5 to 1.7 inches in diameter, with what appears to be just a
single conductor terminal in the form of a clothing snap fastener in the
center of the outside ****tion of the disc. The skin-facing side has
some kind of sensor, about one cm in diameter.
Can these be used for anything interesting, electronics hobby wise?
