A novel approach to transcutaneous localization of blood vessels using a dynamically reconfigurable electrode (DRE) array

摘要: Non-invasive transcutaneous analysis is very desirable in medical applications that require blood analysis. Electrical impedance spectroscopy (EIS) one of the many methods has been extensively researched and often used for such applications, with its advantages including high sensitivity rapid response. EIS utilizes electrodes to monitor conductivity variations blood. However order minimize effect tissue skin surrounding a low impedance, localized subcutaneous vascular structure interest, locate interest then adjust placement size make measurement as targeted possible. It thus essential achieve an appropriate method a) detecting b) localizing so can be improved greatly interfering measurements from disregarded. This study proposes assesses potential use multi-electrode array making dynamically reconfigurable (DRE), by treating electrode segments pixels form re-locating re-shaping electrodes. Simulations preformed COMSOL indicated technique successfully double relative conventional topologies.
