New multi-contact cuff electrodes offer high spatial selectivity for neural recording, enabling precise functional electrical stimulation. This advancement allows distinguishing activity in nerve fascicles as close as 1 mm apart.

Area of Science:

  • Biomedical Engineering
  • Neuroscience
  • Implantable Devices

Background:

  • Closed-loop functional electrical stimulation (FES) systems require advanced neural recording capabilities.
  • High spatial selectivity in neural sensors is crucial for implantable devices to differentiate fascicular nerve information.

Purpose of the Study:

  • To evaluate the feasibility of a novel multi-contact cuff electrode for highly spatial-selective neural recording.
  • To assess the electrode's ability to distinguish neural activity from individual nerve fascicles.

Main Methods:

  • Simulations were performed using a multi-fascicle nerve model.
  • The proposed multi-contact cuff electrode's selectivity was analyzed.
  • Performance was compared against a state-of-the-art electrode.
