Ammonia
Focuses on ammonia concentration monitoring by developing single-walled carbon nanotube (SWCNT) sensors — a low-cost alternative offering approximately ten times the sensitivity and accuracy of commercial products.
Overview
The Ammonia project develops custom Single-Walled Carbon Nanotube (SWCNT) sensors capable of detecting ammonia concentrations as low as 50 parts per billion — approximately ten times the sensitivity of leading commercial sensors. The goal is a low-cost, highly accurate solution for indoor ammonia monitoring in scientific research and safety applications.
Goals
- Test sensors against a variety of hazardous gases to identify further applications
- Develop a reliable calibration methodology to prevent sensor drift
- Explore SWCNT-based applications including handheld instruments, wearables, and embedded gas alarms
Technical Highlights
- Detects ammonia at concentrations as low as 50 ppb
- ~10× the sensitivity of leading commercial sensors
- Sensor thinner than paper — requires ZIF connector for handling
