Cole-Cole Parameter Extraction from Electrical Impedance Spectroscopy for Real-time Monitoring of Vegetal Tissue: Case Study with a Single Celery Stalk

Real-time monitoring of the physiological state of plants using Electrical Impedance Spectroscopy (EIS) may help to optimize their need for watering in order for them to efficiently contribute to urban cooling. This paper presents first results obtained from continuous EIS acquisition during 9 days, applied on a celery stalk, in order to follow it physiological stage. A Cole-Cole modeling is used in order to extract parameter evolution versus time or mass loss of the plant. As a first result, a link is established between the curve shape obtained and the celery stalk tampering.

Automated summary

Real-time monitoring of plant physiological state using Electrical Impedance Spectroscopy (EIS) can optimize water requirements and contribute to urban cooling. This study presents initial results of continuous EIS acquisition on a celery stalk, with a link established between curve shape and tampering of the stalk.
