Nanorod based oxygen sensor

In news

Indian Scientists have developed a nanorods-based oxygen sensor which works at room temperature with assistance of UV irradiation and can detect oxygen gas concentrations in places such as underground mines, at higher altitudes, inside aeroplanes and research labs.

Highlights
  • Monitoring O2 concentration in very low ppm-level is of paramount importance, and a fast and selective oxygen sensor working at room temperature can save lives in places like underground mines, higher altitudes and improve the accuracy of numerous experiments being conducted in research labs.
  • Scientists have fabricated a metal oxide semiconductor (MOS) nanorods array-based oxygen sensor which works at room temperature with assistance of UV irradiation and can detect broad ppm range of oxygen gas concentrations. 
  • The team showed that the sensor gives the best sensitivity with low power consumption and works at room temperature. 
  • The fabricated sensors exhibited response and recovery times of around 3 sec and 10 sec, respectively, at 1000 ppm.
  • The sensor works in oxygen concentrations ranging from 25 ppm to 10 lakh ppm (100%) with good stability.
