Solid State Soil Sensor
Abstract: A solid-state soil nutrient sensor comprising a sensor blade for inserting into the soil, the sensor blade comprising an electrically insulating substrate. The sensor further comprises first and second electrodes disposed on the substrate, each electrode comprising: a sensing region located towards an end of the sensor blade inserted into the soil, and a contact region displaced away from the end of the sensor blade and electrically connected to the sensing region, for making an electrical connection to the electrode. The sensor further comprises electrical insulation over each of the first and second electrodes between the sensing region and the contact region; a reference membrane over the sensing region of the first electrode; and a nutrient sensing membrane over the sensing region of the second electrode; wherein the sensing regions of the first and second electrodes are less than 10 mm apart on the sensor blade; and the reference and nutrient sensing membrane each comprise one or more layers of solvent-cast polymer.
