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.

The researchers believe that microscale electrodes are going to play a key role in the future with more demand for precise and targeted neurostimulation therapy because the electrode technology will better help patients with implantable devices for restoring eyesight, movement, and other lost functionalities.

This is part of the researcher's focus on augmenting and improving implantable devices using nano and microscale technologies for more reliable and advanced treatments.
