this is some 1820s science right here

What.

We have discovered that hard, electrical conductors (e.g., metals or graphite) can be adhered to soft, aqueous materials (e.g., hydrogels, fruit, or animal tissue) without the use of an adhesive. The adhesion is induced by a low DC electric field.

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.

Here’s a video. Holy shit. What.

@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).

Now that’s not something I’d considered. Neat!
