Bio-impedance Modeling of plants

Bio-impedance non-invasive measurement techniques usage is rapidly increasing in the agriculture industry. These measured impedance variations reflect tacit biochemical and biophysical changes of living and non-living tissues. Bio-impedance circuit modeling is an effective solution used in biology and medicine to fit the measured impedance. 

Bio-impedance measurements are used in the diagnosis of plants behaviour to certain conditions such as fruit maturity, fruit ripening, analyzing the effect of heating and freezing conditions on fruits, measuring of root growth, and determining the water content and characteristic analysis of the root zone. Also, it is used to provide information about environmental change effect on fruits. There are other contributions in using bio-impedance measurements for different applications such as blood glucose measurement, monitoring insulin availability for personalized diabetes therapy, Characterising red blood cell micro-circulatory parameters, and tactile sensing bio-hybrid soft E-skin in soft robotics. 

This talk demonstrates the different bio-impedance plant electrical models, measurement methodology and optimization technique suitable for solutions. Extract the best circuit parameters circuit for the model that fit the experimental results via different optimization techniques from mathematical point of view to choose the best performance versus the complexity of the used algorithms.
