Electrical Impedance Spectroscopy on flowing blood to predict white thrombus formation in artificial microchannels

摘要

The “in vitro” study of white thrombus growth by means of Electrical Impedance Spectroscopy on whole blood is presented; the aim of the work is to correlate thrombus formation in an artificial channel with impedance measurements. The measurement bench is composed of a sensor, a switch unit and an impedance meter. Post process of measured data is performed and an equivalent lumped circuit is derived; experimental data are obtained with a first prototype based on a single couple of electrodes.
