| Outline of Final Research Achievements |
A magneto-impedance (MI) sensor was capable to detect faint mechanical vibration in a living body as magnetic field fluctuation at the nanoscale level. Combination of a triaxial MI sensor with a triaxial acceleration sensor enabled to determine the position and posture of a living body in real time from the deviation of the geomagnetism and acceleration.
We also developed a rotary motion testing machine, which consisted of a servomotor and its microcontroller system, Arduino, and could imitate the rotational motion of adductor pollicis muscles. A motion sensor integrating a triaxial magnetic sensor and a magnetic sensor was attached to this testing machine. Thereby, an evaluation device of vibration in a living body was constructed. By using this device, new applications such as the theoretical analysis of adductor pollicis muscle movements, have been developed.
