Abstract
A biological information measurement system includes: a plurality of electrodes; a current source connected to the plurality of electrodes to supply a current thereto; a measurement unit for measuring impedance from a potential difference between the plurality of electrodes; a detector for detecting values of specific peaks from chronological data of the impedance; an envelope generator for generating an envelope of values of the specific peaks; and an output unit for outputting information of the envelope as biological information.
