Proposed sensing system. a) Overview of the proposed sensing system with degradable sensor devices. b) When power is wirelessly supplied to the degradable sensor devices placed on the soil, the device heaters activate. The sensing location is determined from the hotspot location, and the temperature of the heater varies with the soil moisture content; thus, the soil moisture content is measured from the hotspot temperature. c) The degradable sensor devices are tilled into the soil after use. Subsequently, fertilizer components in the substrate of the sensor device are released into the soil, stimulating crop growth.
