Abstract :
Reliable evaluation for the arousal effect of magnetized olivine-crushed-stone-crammed vinyl pipe set on an elderly car driver´s spine has been carried out measuring a four-points electroencephalogram using driving simulators considering a defined arousal index β/(δ+θ) . A sintered-magnetized-spherical-particles-crammed pipe is developed for realization of periodically pulse distributed surface magnetic field train matching with the magneto-protonics principle. Transition of the magnetic field time series generated from the spine with application of the physiological magnetic stimulation have also been measured using the amorphous wire and CMOS IC based pico-Tesla resolution magneto-impedance sensor, in which existence of alternative areas of cooperativeness and anti-cooperativeness for transition of the arousal index each other along the spine length direction is suggested. A special point on the central spine generating a large bio magnetic field of around 10 nT amplitude as well as corresponding pit of the stomach position was found.
