Startup Inbrain Neuroelectronics is experimenting with a brain-computer interface (BCI) using graphene chips. BCIs allow people to control computers directly using brain signals. The company is already scheduled to test its graphene-based BCI this summer at the University of Manchester, during a patient's brain tumor removal operation.
BCIs are far from being a new technology, with Musk's first Neuralink patient now able to play PC games with just his mind. However, what makes the graphene chip a novel solution is that it doesn't use metallic materials. Graphene is made solely from carbon, thus making it insusceptible to faradaic reactions.
