Abstract

Neural recording is one of the main issues to be addressed in order to allow closed-loop functional electrical stimulation systems. Because each fascicle in nerves carry specific information, new sensors providing high spatial selectivity are required for chronic implantable devices. This work aims at evaluating the feasibility of a new device using a highly spatial-selective multi-contact cuff electrode. The proposed electrode configuration is evaluated based on simulations using a model of a nerve comprising multiple fascicles. Study of the electrode selectivity is done and compared with a state-of-theart electrode designed for the same purpose and shows that activity of two fascicles separated by as little as 1mm can be distinguished. Implementation challenges and perspectives for such electrodes are also discussed.
