Abstract
Most natural phenomena are explained by complex systems science. Since tactile sensing is dominated by the nonlinear contact problem between object and finger surfaces and is recognized in nonlinear brain systems, it is closely related to complex systems science as well. We consider two phenomena caused by complex systems related to tactile sensing: Stochastic Resonance (SR) and tactile illusions. Elucidation of these mechanisms provides important hints to develop robotic tactile sensors and tactile displays. Since tactile sensing is performed by contact and brain activity, both mechanical analysis and neuron simulations are required to elucidate the complex systems phenomena in tactile sensing. In this paper, we outline our continuing project and neuron simulations using a Hodgkin-Huxley model.
