Abstract

Electrical Impedance Spectroscopy, EIS, is widely used in the study of electrical properties and structure of biological tissues, namely in quality control of fruits and the characterization of specific botanical tissues. The present work aims to extend the EIS concept to identify structure damaging pathologies for in vivo vegetal tissue. This allows for the early detection of specific plant diseases with economic and environmental impact. Moreover, the commercially available EIS solutions miss a true frequency bandwidth analysis and, despite the general good performance, are unspecified for bioimpedance measurements and are often quite expensive. Consequently, these limitations are the main reason for erroneous interpretations and inaccurate results. Therefore, this work proposes the development of a dedicated bioEIS system, characterized by an appropriated frequency range (1kHz to 1MHz), suitable for biological applications, in such a way that it becomes possible to compensate the influence of potential errors in off-line analysis.

生物电阻抗光谱技术在植物病害早期检测与监测中的应用

电阻抗谱(EIS)广泛应用于研究生物组织的电学性质和结构，即果实的质量控制和特定植物组织的表征。目前的工作旨在扩展EIS概念，以识别体内植物组织的结构损伤病理。这使得能够早期发现具有经济和环境影响的特定植物病害。此外，商业上可用的EIS解决方案缺少真正的频率带宽分析，尽管总体上性能良好，但不适合生物阻抗测量，而且往往相当昂贵。因此，这些限制是错误解释和不准确结果的主要原因。因此，本工作建议开发一种专用的生物eis系统，其特点是适当的频率范围(1kHz至1MHz)，适合于生物学应用，这样就可以补偿离线分析中潜在误差的影响。
