Chemiresistive percolation gas sensor

Applications: Gas monitoring, sensing disease markers, identification of volatile compounds, medical devices, measurement.

Features	Benefits
Uses electrochemical technology instead of optical absorption, chromatography or spectrometry.	Sensors are more robust and cheaper than current technology.
Current sensor limit of detection results: 18 ppb for NH₃ in N₂; 0.9 ppm for NO₂ in N₂.	More sensitive than existing chemiresistive sensors.
Response time: 5 sec.	Faster response times than optical absorption, chromatography and spectrometry or other optical probes.
Active sensor area: 5 mm diameter.	The sensor has a compact form factor.
Typical power consumption: 0.1 mW.	Low power requirements.
