Abstract
In a device for measuring motion of living body organs, an essential part which defines the oscillation frequency of the oscillator circuit of the device for measuring same comprises an electro-mechanical oscillator of a quartz resonator and impedance elements as coils or capacitors. The motion of organs on a living body surface or in a living body causes impedance changes in an impedance element and therefore, the detector is capable of detecting and measuring living body organ motion through a change in frequency.
