Most importantly: it stays stuck with the voltage turned off. It’s stable for MONTHS. Reverse the polarity of the electrical flow and it unsticks. YES REALLY. This is some literal “Alessandro Volta playing around with bananas in a shed” science AND YET it WORKS and we DID NOT KNOW.
Sadly I think skin will be a fairly poor use; you’d have to go down multiple dermal layers before getting to tissue that I think might work, and even then, you’d be dealing with new layers of skin growing out and old layers being pushed off and dying.
@solarbird That might be useful for positioning stuff using the micron-scale probe on the μRepRap as micron-scale moving parts are a bugger (until the μRepRap gets going anyway).
@fishidwardrobe More seriously, I'm pretty sure that would work with gels of the appropriate ionic content. But first, the micron printer mechanism... @solarbird
