Abstract

Monitoring nitrogen utilization efficiency and soil temperature in agricultural systems for timely intervention is essential for crop health with reduced environmental pollution. Herein, this work presents a high-performance multi-parameter sensor based on vanadium oxide (VO_X )-doped laser-induced graphene (LIG) foam to completely decouple nitrogen oxides (NO_X ) and temperature. The highly porous 3D VO_X -doped LIG foam composite is readily obtained by laser scribing vanadium sulfide (V₅ S₈ )-doped block copolymer and phenolic resin self-assembled films. The heterojunction formed at the LIG/VO_X interface provides the sensor with enhanced response to NO_X and an ultralow limit of detection of 3 ppb (theoretical estimate of 451 ppt) at room temperature. The sensor also exhibits a wide detection range, fast response/recovery, good selectivity, and stability over 16 days. Meanwhile, the sensor can accurately detect temperature over a wide linear range of 10-110 °C. The encapsulation of the sensor with a soft membrane further allows for temperature sensing without being affected by NO_X . The unencapsulated sensor operated at elevated temperature removes the influences of relative humidity and temperature variations for accurate NO_X measurements. The capability to decouple nitrogen loss and soil temperature paves the way for the development of future multimodal decoupled electronics for precision agriculture and health monitoring.

Keywords: multi-parameter sensors; nitrogen loss and soil temperature monitoring; precision agriculture; vanadium oxide-doped laser-induced graphene foam.
