Abstract

The invention belongs to the field of biological impedance measurement, and particularly discloses a biological impedance measurement probe, measuring system and method based on a spectral characteristic. The measurement probe comprises a substrate and at least six electrodes embedded in the substrate, the six electrodes comprise the first electrode, the second electrode, the third electrode, the fourth electrode, the fifth electrode and the sixth electrode, the first electrode is arranged opposite to the fourth electrode or / and the second electrode and the fifth electrode or / and the third electrode and the sixth electrode, excitation is carried out between any oppositely-arranged electrodes, the electrodes are distributed on the substrate in a circumferential array mode, and at least two electrode pairs in axial symmetry are formed. Therefore, the probe has the advantages of being stable in signal collection and simple in structure. The biological impedance measurement system and method based on the spectral characteristic are further provided, therefore, the influence of contact resistance between the probe and measured tissue can be reduced effectively, and the accuracy of judging whether the probe is arranged at the junction of human body tissue or animal body tissue is improved.

Description

technical field [0001] The invention relates to the field of bio-impedance measurement, in particular to a bio-impedance measurement probe, measurement system and method based on spectral characteristics. Background technique [0002] The impedance frequency characteristic of biological tissue, also known as the impedance spectrum (Impedance spectroscopy) characteristic, mainly refers to the value of resistive and capacitive components in the electrical impedance of biological tissue that will change significantly with the frequency of the applied electrical signal . Since biological impedance is closely related to the measurement frequency, in the audio frequency range, the characteristics of its impedance changing with frequency are closely related to its cell morphology, cell arrangement, intercellular substance content and electrolyte concentration. Therefore, obtaining the electrical impedance characteristics of tissues or organs in this frequency band has important ap...
