Summary:The monitoring and control of soil moisture has always been the subject of attention of both developers of sensor elements and agro-engineers. New developments are available on the market, using different methods, with different functionalities, accuracy and price. This article proposes an innovative approach for non-contact measurement of soil moisture using capacitive flexible sensors. Three different forms of capacitive structures printed with Inkjet technology, silver nanoparticle ink and PET substrate were studied. The results for the change of the capacity and impedance of the structures when the soil moisture changes are presented.
