The palm of the hand is very sensitive to galvanic changes, so it is therefore the area of choice. To secure the dime electrodes to the palm of the hand I made a small palm-fitting electrode holder out of ¾ inch pinewood. You only need a couple of square inches practically any piece of scrap can be used, see drawing. After cutting the wood to the proper shape, drill a ¼ inch hole through the center as shown to feed the cable through. Then glue, epoxy or hot glue the electrodes to the wood block as shown. To finish off the hand electrode, attach a rubber band or elastic material to the base so that it covers the electrodes. This material is what will secure the holder to your hand.
