IMPEDANCE METHODS AND APPARATUSES USING ARRAYS OF BIPOLAR ELECTRODES

摘要

Apparatuses and methods for analyzing a region of a body (including a human body) by electrical impedance, using electrodes driven for bipolar stimulation (bipolar electrodes) and determining a frequency response in electrical properties at a plurality of sub-regions beneath an array of the bipolar electrodes that has been placed on a surface of the body. In particular, the methods and apparatuses described herein may be used to determine tissue wetness based on the change across frequencies based on bio-impedance measured with an array of bipolar electrodes.
