摘要

本文提出了一种用于细胞培养物二维处理的生物阻抗测量新方法。它允许通过使用一种新的阻抗传感方法来表示生物样品，并利用电极-细胞模型进行电模拟和成像重建。初步的电学模拟报告验证了电池阻抗谱(ECIS)应用的建议。实验结果表明，利用所提出的CMOS系统可以在多个频率下正确地检测和显示低浓度的细胞培养。

A CMOS bio-impedance measurement system

This paper proposes a new method for bio-impedance measurement useful to 2D processing of cell cultures. It allows to represent biological samples by using a new impedance sensing method, and exploiting the electrode-to-cell model for both electrical simulation and imaging reconstruction. Preliminary electrical simulations are reported to validate the proposal for Electrical Cell Impedance Spectroscopy (ECIS) applications. The results reported show that low concentration cell culture can be correctly sensed and displayed at several frequencies using the proposed CMOS system.
