Arousal Effect of Physiological Magnetic Stimulation on Elder Person's Spine for Prevention of Drowsiness During Car Driving

A new method for the prevention of drowsiness of eldery people during car driving is presented, in which a distributed-pulse magnetic field generated from a magnetized fayalite crushed stone crammed pipe is applied to their spine position. The effect for arousal is evaluated by measuring the subject's back head magneto-encephalogram fast Fourier transform frequency spectra using a pico-Tesla resolution magnetoimpedance sensor and by using an electro-encephalogram meter before and after magnetic stimulation. The effect for arousal during car driving is evaluated by using a driving simulator to measure the car body deflection from a driving road line and observation of the driver's sleepiness. Mechanisms for the arousal effect are discussed with the magneto-protonics principle on the basis of the arousal physiology and measurement of the magnetization of a physiological saline solution before and after application of the magnetic pipe.
