Graphene Monolayer Improves Implantable Neurostim Devices

One of the most commonly used elements in neurostimulation devices is platinum microelectrodes, but they are prone to corrosion, which can reduce the functional lifetime of the devices. Researchers have come up with a solution to help: adding a graphene monolayer to the devices to protect the microelectrodes. The graphene monolayer is an effective diffusion barrier and electrical conductor.
