“…As a hotspot corresponds to a sensor-device location, the sensing position is determined precisely based on the relative position of the camera and the ground surface. [26][27][28] Moreover, the sensor devices are composed of eco-friendly materials, most of which biodegrade in the environment, and the residual components are unlikely to adversely affect the environment. Following a certain period of usage (e.g., one season), the devices can be tilled into the soil.…”

“…Image recognition is a promising technology for simplifying sensor-device design and achieving the accuracy required for medium-range position acquisition. [26][27][28] The developed sensor device successfully transmitted the sensed soil moisture content to the outside environment via heat generation. Therefore, the sensor position and soil moisture content could be simultaneously determined from the heater temperature by observing the sensor-device installation position using a thermal camera.…”

Sensor networks comprising small wireless sensor devices facilitate the collection of environmental information and increase the efficiency of outdoor practices, including agriculture. However, the sensor‐device installation density of a network is limited because conventional sensor devices must be removed after use. In this study, a sustainable dense sensing system that combines simplified degradable sensor devices, wireless power supply, and thermal‐camera image‐based information recognition is proposed. The proposed wireless‐power‐driven sensor device comprises a biodegradable nanopaper substrate, natural wax, and an eco‐friendly tin conductive line. The sensor device emits a thermal signal based on the soil moisture content. The thermal camera simultaneously acquires the soil moisture‐content data and sensor‐device location. The majority of the sensor‐device components are biodegradable, and the residual components have a minimal adverse impact on the environment. Additionally, the fertilizer component in the substrate promotes plant growth. The proposed sensing concept introduces a novel direction for realizing hyperdense sensor networks and contributes to the development of social systems that combine sustainability with meticulous environmental management.
