Neural Prostheses

Restoration of Hand Dexterity

Our specific objectives in this program are to create a platform of scientific investigation for nerve injury and functional restoration, provide proof-of-concept feasibility of the technology in a non-human primate model, and take the technology to the patient to facilitate commercialization. One of the primary limitations of current neuroprostheses that aim to restore motor function is a reliable nerve-electrode interface that can be used over a long period of time to record and distinguish multiple patterns of nerve signals proximal to the injury in order to decipher intended movements with sufficient degrees-of-freedom.

Our complete system for restoring hand dexterity will be composed of four components, illustrated in the schematic below:

  1. Neural interface equiped with nerve electrodes and implanted amplifier unit
  2. External receiver and decoding unit
  3. Battery unit and transmiter for providing wireless power to muscle stimulating electrodes
  4. Implanted muscle stimuating electrodes for actuating hand movemement

The end goal: fully integrated and implantable system
