Neural signal sensing from spinal cords and periphery nerves

This paper gives an introduction on the neural signal sensing of the system of microelectronic-embedded channel bridge and signal regeneration of injured spinal cords and periphery nerves. For neural signal sensing, electrode arrays of both cuff and needle types were used. For neural signal amplifying, the circuits realized with discrete devices and in CMOS process will be discussed. The application of the sensing circuits in a neural channel bridge system will be demonstrated.
