description |
We analyzed and organized the reasons why the amorphous wire CMOS IC magneto-impedance sensor
(MI sensor) has rapidly been mass-produced as the electronic compass chips for the smart phones, mobile phones,
and the wrist watches. Comprehensive advantageous features regarding six terms of (1) microsizing and ultralow
power consumption, (2) high linearity without any hysteresis for the magnetic field detection, (3) high sensitivity
for magnetic field detection with a Pico-Tesla resolution, (4) quick response for detection of magnetic field, (5)
high temperature stability, and (6) high reversibility against large disturbance magnetic field shock are based on the
magneto-impedance effect in the amorphous wires.
We have detected the biomagnetic field using the Pico-Tesla resolution MI sensor at the room temperature such as
the magneto-cardiogram (MCG), the magneto-encephalogram (MEG), and the self-oscillatory magnetic field of
guinea-pig stomach smooth muscles (in vitro) that suggest the origin of the biomagnetic field is probably pulsive
flow of Ca2+ through the muscle cell membrane. |
