Maybe everyone else has already sorted this out themselves already, but I just recently wanted a touch switch, and was looking around for a way to do that. I started out looking for simple circuits to do it... and then stumbled on a part that pretty much does all the work.
MTCH101 - SOT-23-6, with one touch channel (sensitivity adjustable with an analog voltage) and an open drain output. Also has a low power mode. I am using a board I bought a while ago (man, someone made some money off me, that chip costs practically nothing!) that I finally found which uses one, and it's delightful. I've ordered some, and plan to test whether they can be made to work under less optimal board layouts. It would be awesome if they could be plunked down onto the original Espruino board's prototyping area, or my protoboard.
I'll be getting them late next week, along with some CY8CMBR3002's, which are a 2-channel cap sensor.
