Two Points Simultaneously Measurement of Skin Impedance Based on Triple-Electrode

Acupuncture points and skin impedance.

OVERLAPPING OF MERIDIAN AND VEIN A superficial vein named the median vein located on the midline of the anterior forearm is a common site for phlebotomy. It is rather parallel to the invisible PC4 and pericardial meridian (figure 1), although individual mappings of the vein are not uniform. The veins have thin elastic walls and blood flowing inside; electrically they are very conductive. Mechan...

Electrode-less measurement of cell layers impedance.

This paper is devoted to yet unpublished electrode-less methods (ELM) of cell layers impedance measurement based on transformer principle. The main advantage of ELM is elimination uncertainties caused by interface between electrodes and measured electrolyte. The method of avoiding distortion caused by non-ideal transformer transfer function ("deconvolution") and errors caused by residual voltag...

Real-time measurement of electrode impedance during intracochlear electrode insertion.

OBJECTIVES/HYPOTHESIS This pilot study details the use of a software tool that uses continuous impedance measurement during electrode insertion, with the eventual potential to assess and optimize electrode position and reduce insertional trauma. STUDY DESIGN Software development and experimental study with human cadaveric cochleae and two live surgeries. METHODS A prototype program to measu...

Skin-electrode impedance and its effect on recording cardiac potentials.

Determination of the Parameters of the Skin-Electrode Impedance Model for ECG Measurement

Medical practitioners rely heavily upon the information obtained from electrocardiography. Some seriously ill hospital patients have their ECG constantly monitored throughout their stay, where accuracy in monitoring is essential to maintaining a high level of patient care. Fidelity in the measurement of the electrical activity of the heart is of primary importance for accurate diagnosis and tre...
