  • This paper examines the effect of electrode width and spacing of interdigitated electrodes (IDEs) for impedance-based cancer detection and characterization. IDEs are desired for bioimpedance measurements because their fabrication process is simple and inexpensive, and the geometry presents a potential for improved sensitivity over other microelectrode designs. Optimizing the geometry will eliminate this problem and increase the sensitivity of these devices for bioimpedance measurement applications. This paper evaluates the effect of IDE geometry on the sensitivity of breast cancer cell impedance measurements. Equivalent circuit data analysis was conducted to quantify and characterize the cells. © 2010 IOP Publishing Ltd.
