Here's a followup on that conductive tattoo that william showed thursday -- they claim that this paint is non-toxic, i'd like to see the ingredients. The conductive paint we have found has some toxicity.
the second link isnt actually tattoo but implant but poses some interesting possibilities and issues -- obviously the video in the second is not real, would have liked to see the research with the mouse.
