Abstract

In this paper first approach to a compact system for point-of-use primarily blood characteristics analysis by means of an EIS (Electrochemical Impedance Spectroscopy) experience is described. This is based on a custom electronic instrumentation, post processing software and a commercial three electrodes gold sensor. The designed electronic is based on a potentiostat instrumentation supported by a real time platform connected to a remote computer, which allows the instrumentation control, real time monitoring data and its posterior resultant analysis. Moreover, the whole system has been characterized and validated using different sensors and biocompatible materials. The study consists on a complete EIS experience in order to get a full spectrum analysis of impedance behavior in terms of magnitude and phase. As a result, we were able to detect impedance with an average error of less than 3% and a SNR rejection of -40 dB in a frequency working range of 10 Hz to 100 kHz. This integrated approach pushes forward the development of truly autonomous point-of-care devices relying on impedance spectrometry detection.
研制一种便携式EIS血液分析装置
本文首先介绍了利用电化学阻抗谱(EIS)经验建立一个用于使用点主要血液特征分析的紧凑系统的方法。这是基于定制的电子仪器,后处理软件和商用三电极金传感器。所设计的电子系统以恒电位仪为基础,由连接到远程计算机的实时平台支撑,实现仪器控制、实时监测数据及其后验结果分析。此外,整个系统已经用不同的传感器和生物相容性材料进行了表征和验证。该研究包括一个完整的EIS经验,以获得阻抗行为的幅度和相位的全频谱分析。因此,我们能够在10 Hz至100 kHz的频率工作范围内以平均误差小于3%和信噪比抑制-40 dB的方式检测阻抗。这种集成的方法推动了依赖于阻抗光谱检测的真正自主的护理点设备的发展。
