Connector-tube interface is where very easily to occur thrombus formation in extracorporeal blood circulating system. For early detection of thrombus formation at the connector-tube interface, connector sensor was developed (by incorporating sensing electrodes on the connector). The aim of this study is to improve the electrode shape of the connector sensor for quantitative evaluation of thrombus. In this study, three types of electrode shapes were devised and evaluated using finite element method (FEM) simulation. The measurement area of each electrode was found from the current density distribution image. Also, simulations were performed with various types of thrombus, and the relationship between the thrombus volume and the change in permittivity was compared to clarify the electrode performance. From these simulations, it was found that the type of connector sensor using two arc-shaped electrodes is most suitable for thrombus quantitative evaluation.
