Low-Cost Paper Sensor for Surveillance of Cereal Crops

Jun Kameoka of Texas A&M University in the U.S. will develop multiplex, battery-less and wireless durable paper sensors for positioning under the soil in crop fields to detect the early signs of pests and diseases, and communicate the data to overhead drones via radio frequency to improve pest management. The sensor will be designed to monitor physical, biological and chemical soil conditions that are altered by plant diseases. They will test its performance in commercial garden soil with maize and sorghum plants in a vinyl house.
