Monitoring of thrombus formation in mock extracorporeal circulation system using electrical impedance spectroscopy

An accurate position measurement approach for a single particle in a channel using electrical impedance spectroscopy

“…In the same way, we set 𝑥 = 0, 𝑦_𝑐 is generated randomly range from -2 to 2, and 100 positions are also generated for simulation. Then 𝑦_𝑐 with the impedance are fitted by a curve like a parabola going upwards as shown in Figure 3(b) and Equation (5). Figure 3 only shows the impedance distribution in x and y directions when the excitation frequency f = 500kHz, actually the impedance distribution in x and y directions follows the same law at each frequency, Equation (4) and Equation ( 5) with several parameters are also applicable at each frequency.…”

“…In recent years, electrical impedance technology has been widely used for particle measurement due to its label-free, noninvasive and low-cost properties [1][2][3]. Electrical impedance technology is very simple and has wider application scenarios, especially for real-time imaging and long-time monitoring [2,4,5]. It is a promising technology to estimate the position of a single particle in fluids.…”
