Artificial Spinal Cord IC with Pulse-Type Hardware Neural Networks Mimicking Function of The Spinal Cord

Abstract

An artificial spinal cord IC for motor neuron control using an analog CMOS circuit instead of a conventional digital system is reported. A circuit configuration was proposed for P-HNNs for quadrupedal walking control to enable reflex movements by sensors. It was shown that the gait pattern was changed by actual measurement. Pulse-type hardware neural networks (P-HNNs) were proposed to control human biped gait. The proposed circuit was confirmed to generate walking and running patterns.
