Detection of Human Microvibration Transmitted along Solid Using Pico-Tesla Magneto-Impedance Sensor



Human microvibration waveforms are sensitively detected using a newly developed pico-Tesla magneto-impedance sensor (pT-MI sensor) when the human skin is touched directly or indirectly via transmission solid by the sensor head. The origin of the microvibration is discussed, considering the cellular Ca2+ flow oscillation for the smooth muscle autonomous vibration. Copyright © 2010 Institute of Electrical Engineers of Japan.
