Artificial stimulation of human motor nerves at present is carried out by externally powered electrodes placed on the skin surface (transcutaneous) or under the skin (subcutaneous) in closer proximity to muscles or nerves. We are modelling the use of wireless, ultrasound-harvesting, implanted nanodevice arrays with electrodes for selective stimulation of peripheral nerves in the limbs of the human body. The nanodevice arrays will be embedded in a patch of biocompatible tissue to minimise the risks of inflammation or rejection. This approach provides a longer-term implant solution for nerve stimulation that allows the patient greater freedom of movement than with embedded wired electrodes.
In the future, we believe wireless stimulation will have a greater role in treating debilitating neural conditions, compensating for nerve damage and enhancing prosthetic control. Treating these conditions would entail the deployment of nanodevice arrays not only in the peripheral nervous system but also in the central nervous system (e.g. spinal cord) and possibly on the surface of the brain.
