An impedance measuring device and a health management device using the same

摘要

A device (10,10a) for providing data as a guide to health management is capable of electrical measurements of the subject while he or she is grasping handgrips (12,13) with which the device is equipped. Once measurement has begun, the impedance variability measured by the device is calculated at every sampling period, and if the value of this variability is less than a predetermined amount over a number of samplings, it is concluded that the electrodes (17,18) which apply a fixed current and the electrodes (19,20) which detect voltage are making good contact with the subject's hands.
