Abstract
Neural electrode with microchannel structure that carries nerve growth factor (NGF) is suggested for the peripheral nerve interface. In order to overcome the degradation of the electrode due to the glial scar formation, neural electrode with microchannel was fabricated. Electrochemical characterization was performed on the gold patterned electrodes and observed low electrochemical impedance (503.9􀀁 􀀃 ) suitable for neuronal recording. Fabricated neural electrode was implanted in the sciatic nerve of the rat to observe the feasibility of chronic implantation and signal acquisition.
