Scalable Photoactive NO₂-Sensing Framework for Plant Health Monitoring.

ABSTRACT: Conventional sensing platforms for plant health monitoring are often limited by high operating temperatures, rigid substrates, and poor compatibility with ambient, power-constrained, or biologically sensitive environments. These limitations hinder their integration into emerging platforms such as smart agriculture and plant-interfaced electronics, where mechanical flexibility, energy efficiency, and low thermal budgets are essential. This paper reports a scalable, thermally passive NO₂ sensor based on light-activated 3D TiO₂ nanoarchitectures. Fabricated via sequential glancing angle deposition, the highly ordered porous nanoarchitectures exhibit tunable broadband light scattering and defect-mediated sub-bandgap activation under ambient light.
