2A1-A14 Improvement of tactile perception capability by stochastic resonance effect : Discussion based on a summing network model(Tactile and Force Sensing (1))

Abstract

This paper reports experimental results on surgical grasping forceps with a vibration actuator that enhances a tactile perception ability. A passive sensory test has been conducted for human participants to confirm the efficacy of the device. Statistical significance has been observed when appropriate noise is applied. To investigate the effect of the noise intensity, a summing network of FitzHugh-Nagumo model neurons was built. The simulation results showed that a network with relatively large units improves the detection capability of the input signal.
