Abstract

An organism vibration measuring device is for measuring a vibration of a portion of an organism which is put in an alternating magnetic field. The organism vibration measuring device includes a vibration detecting member, having a structure suitable for attachment to the portion of the organism, for detecting the vibration of the portion of the organism which resonates under an influence of the alternating magnetic field. It further includes a vibration measuring member for measuring the vibration state of the portion of the organism on the basis of a detection signal from the vibration detecting member.

Claims

1. An organism vibration measuring device for measuring a vibration of a portion of an organism which is put in an alternating magnetic field, comprising:

a vibration detecting member, suitable for attachment to the portion of the organism, for detecting the vibration of the portion of the organism which resonates under an influence of the alternating magnetic field; and

a vibration measuring number for measuring a state of the vibration of the portion of the organism on the basis of a detection signal from the vibration detecting member.

2. An organism vibration measuring device as claimed in claim 1, further comprising an alternating magnetic field generator for generating the alternating magnetic field.

3. An organism vibrating measuring device as claimed in claim 2, wherein the alternating magnetic field generator comprises an AC electromagnet.

4. An organism vibration measuring device as claimed in claim 1, wherein the vibration detecting member includes a ring suitable for attachment to a finger, the finger being the portion of the organism.

5. An organism vibrating measuring device as claimed in claim 1, wherein the ring is made of non-conductive material and includes a C-shaped section.

6. An organism vibration measuring device as claimed in claim 1, wherein the vibration detecting member comprises an acceleration sensor.

7. An organism vibration measuring device as claimed in claim 1, wherein the vibration detecting member comprises a ring suitable for attachment to a finger, the finger being the portion of the organism, and an acceleration sensor attached to the ring.

8. An organism vibration measuring device for measuring a vibration of a portion of an organism which is put in an alternating magnetic field, comprising:

vibration detecting means for detecting the vibration of the portion of the organism which resonates under an influence of the alternating magnetic field; and

vibration measuring means for measuring a state of the vibration of the portion of the organism on the basis of a detection signal from the vibration detecting means.

9. An organism vibration measuring method for measuring a vibration of a portion of an organism, comprising the steps of:

subjecting the portion of the organism to an alternating magnetic field;

resonating the portion of the organism under an influence of the alternating magnetic field;

detecting vibration of the portion of the organism; and

determining a vibration state of the portion of the organism on the basis of the detected vibration.

10. An organism vibration measuring method as claimed in claim 9, wherein the portion of the organism is a muscle of a finger.

11. An organism vibration measuring method as claimed in claim 9, further comprising a step of analyzing an effect of the magnetic field on the portion of the organism, on the basis of the determined vibration state of the portion of the organism.
