On further inspection there is 'one' more flaw, The 'tissue' membrane would require routine maintenance as it WILL collect undesirable elements fron the skin of the subject... skin oils and skin particles as well as perspiration residues. The point here is that the tissue paper solution was offered as a means of avoiding current flow through the skin of the subject. There are several methods of solving this problem that minimize or eliminate the current flow issue. This part of this thread somehow misses the origional concept, That is that a current of 5 to 10 ľa (being 1 to 5% of the threshold of detection) is reasonably non intrusive and not likely to be any kind of health or other physiological issue...
