I have expanded on >this somewhat in my off-list answer to Imre. :*) Shame on you for coming up with such a device. Anyway, since I have not seen it mentioned, Jim Thompson (whom I greatly respect) has a design for an earlobe pickup device on his site: http://www.analog-innovations.com/Earpulse.pdf It works with both (all?) genders and any skin colo[u]r so it is a perfectly acceptable circuit. No expensive parts, either, so it's also suitable for the economically disadvantaged.
