Biomimetic soil biophysical redox monitoring sensors
Innovative biomimetic sensors for real-time monitoring of root oxygen bioavailability and soil oxygen levels, simulating root respiration. These sensors differentiate between soil hydration levels, supporting agriculture and environmental monitoring.
Overview
The biomimetic soil biophysical redox monitoring sensors offer a novel approach to agricultural and environmental monitoring by directly measuring root oxygen bioavailability (ROB) and oxygen concentrations. Developed to mimic root tissue respiration, these sensors provide real-time differentiation between hydrated and flooded soils, acting as a biophysical integrator of soil stress conditions. The technology is applicable in both soil and hydroponic systems, offering valuable insights into water stress, irrigation efficiency, and soil health.
Technical specifications
- Biomimetic design: Mimics root tissue respiration to assess oxygen bioavailability accurately.
- Real-time monitoring: Differentiates between aerobic and anaerobic conditions to detect overirrigation or soil flooding.
- Integration capabilities: Can be integrated with soil water sensors and Field Flux sensors for tracking photosynthetic CO2 flux.
- Scalable deployment: Distribution of point-of-contact sensors enables field-level monitoring and comparison with satellite remote sensing data.
- Prototyped and patented: The technology has been prototyped, patented, and is ready for further development and commercial partnerships.
Technology readiness level
Currently at Technology Readiness Level 5, this technology is in the prototyping and testing phase. Future plans include developing 3D manufacturing capabilities, field and hydroponics testing, and integration with existing sensor systems and remote sensing for comprehensive validation.
