Physiological magnetic stimulation on car driver's spine for arousal without rebound sleep preventing drowsy driving and back-magnetocardiogram

We have found a remarkable arousal effect for car drivers preventing drowsy driving with application of a magnetized particle train (named “physiological magnetic stimulation”; PMS) on their spine position during operation of a driving simulator (DS) and discussed on the physiological mechanism with measurements of the spine bio-magnetic field using a Pico-Tesla resolution magneto-impedance sensor (PT-MI sensor) [1], [2]. We newly concluded from experimental results with 115 subjects that the PMS is not only effective but also safe without “rebound sleep” which is induced to drop into a deeper sleep within several minutes after application of the sensory stimulation such as the alarm sound and the mechanical vibration as illustrated in Table 1. We also found a remarkable change of waveform of the bio-magnetic field time series detected at the left shoulder blade bottom position (Back Magneto-cardiogram) using the PT-MI sensor with application of the PMS on the spine position, with which a regulation of the blood circulation system was suggested in the FFT spectrum analysis.
