Abstract:: Abstract: This report presents a new design for electrica nervel stimulation system based on Rössler chaotic model, and describes the design principles, procedures and test methods. The result shows that the chaotic signal is an ideal signal source in the electrical nerve stimulation. The regularity of chaotic signals provides comfort for patients during treatment, and the randomness within chaotic signal maintains the diversity of the electrical stimulation. Various electrical simulation effects are achieved by varying the chaos equation parameters. In order to explore the application advantages of chaotic electric stimulation, a non-contact measurement system based on machine vision is designed. The experimental results show that the chaotic electric stimulation can make the frog leg maintain continue vibration in a large amplitude, with potential application advantages, while the periodic stimulation (continuous wave and sparse-dense wave) attenuates the jitter of the frog leg faster, which may be due to the delay in the generation of tolerance or the reduction of the fatigue level of electrical stimulation because of the chaotic electrical stimulation. Chaos model makes the rules and diversity be included in electrical stimulation procedure and improves the performance of the current commercially available electrical stimulator. The unified mathematical model provides a new direction for the standard of the current electrical stimulation parameters.
