Neural prostheses are exciting researchers, but silicon based devices are difficult to integrate with soft tissue. Now researchers from the Technische UniversitÃ¤t MÃ¼nchen in Germany are experimenting with graphene based neural prostheses, saying that graphene has excellent biocompatibility.
The researchers have shown that it's possible to make graphene based transistors that are gated by the solution in which the transistor sits. In other words, the natural body fluids that surround these prostheses will form an integral part of their operation. Those "solution-gated transistors" far outperform other technologies.
