NEXT GENERATION CYBERNETICS: LONG TERM CARBON FIBRE DUAL STIMULATION / RECORDING ELECTRODE ARRAYS FOR CLOSED LOOP NEURAL IMPLANTS
Grant number: 1101717 | Funding period: 2016 - 2021
Electrodes implanted in the brain have enormous potential for treating a range of conditions from epilepsy to control of prosthetics for patients with limb loss. Currently, the electrodes used in such system fail rapidly because they are rejected by the body. We aim to use diamond with ultra-fine carbon fibre electrodes to make arrays that are invisible to the human immune system. Such arrays will function for the lifetime of the patient without needing replacement.
