UMass Amherst engineers have built an artificial neuron powered by bacterial protein nanowires that functions like a real one, but at extremely low voltage. This allows for seamless communication with biological cells and drastically improved energy efficiency. The discovery could lead to bio-inspired computers and wearable electronics that no longer need power-hungry amplifiers.
Maybe. If you’re talking about the invasive forms of BCI (ie not EEG) then it could be better. Biocompatibility is difficult, the article doesn’t go super in depth, but assuming they don’t get attacked by the immune system then maybe. But you still have to implant them by opening up the skull so there is that.
