Abstract
A sensor uses microneedle electrodes and multi-frequency electrical impedance spectroscopy to monitor plant water status in real time. The microneedle can be between 10 and 1000 microns in length, enabling precise placement in a variety of plant tissues. The impedance behavior can distinguish electrical properties and physiological functions of different plant tissue types. Therefore, impedance measurements can be used to monitor water stress to prevent irreversible damage to a plant and to enable improvement of plant biomass or fruit yield.
