SoilNutri: A Passive Metasurface-based, Low-cost System for Soil Moisture and Nitrogen Monitoring

Published:

Conference: UbiComp 2026

SoilNutri is a battery-free passive metasurface sensing platform for scalable soil monitoring. The system leverages RF spectral responses to estimate soil moisture and nitrogen concentration using low-cost sensors that can be deployed at scale without batteries or maintenance.

Highlights

  • Battery-free passive sensing for long-term deployment
  • Simultaneous soil moisture and nitrogen monitoring
  • Low-cost metasurface sensor design
  • Scalable environmental intelligence for agriculture
