Internal repair robots for our robowaifus, at some point?
>MIT engineers have discovered a new way of generating electricity using tiny carbon particles that can create a current simply by interacting with liquid surrounding them. ...
>To harness this special capability, the researchers created electricity-generating particles by grinding up carbon nanotubes and forming them into a sheet of paper-like material. One side of each sheet was coated with a Teflon-like polymer, and the researchers then cut out small particles, which can be any shape or size. For this study, they made particles that were 250 microns by 250 microns.
>When these particles are submerged in an organic solvent such as acetonitrile, the solvent adheres to the uncoated surface of the particles and begins pulling electrons out of them.
>Strano’s lab has already begun building robots at that scale, which could one day be used as diagnostic or environmental sensors: https://scitechdaily.com/nanoscientists-create-smallest-robots-yet-that-can-sense-their-environment/
