The stochastic resonance (SR, hereafter) is one of the basic principles intrinsically possessed by any living thing to highly adapt for the complicated environment including various disturbances. It was found that Hodgikin-Huxley model capable of emulating living neuron activity shows the SR. A system of two differential equations dominating Hodgikin-Huxley model is similar to a differential equation system for Belousov-Zhabotinsky (B-Z, hereafter) reaction, which is one of phenomena caused by complex science systems. Although a noise is mixed inevitably by contact with an object and sensor's movement on it in tactile sensing, a human being can evaluate the several micrometers unevenness on the object surface by means of the SR. If the SR mechanism is incorporated into a tactile sensing system, the system can measure an object surface with high precision in not only the controlled environment adjusted like a precision measurement room but a living environment In our laboratory, we intend to apply remarks obtained from complex science systems such as SR and B-Z reaction to robotic systems such as a tactile sensing system and a tactile display. Some resent topics of our results are described in the presentation of HP 2008.
