At the Photonics Laboratory in IIT Bombay, we are developing various photonic devices based on different spectroscopic techniques. They are tailored for various opto-electronic and sensing applications in the agricultural, healthcare and environmental sector. One such device is the Gas sensor for environmental monitoring system based on ZnO hybrid microcrystal.

Motivation    
■ Highly responsive and regenerative Oxygen gas monitoringsensing platform for oxygen deficient places like mines,spacecrafts, etc.
Novelty
■ Easy to chemically synthesise
■ Lap-on-chip hand-held portable device
Salient features    
■ Highly sensitive; can sense pressure variations as low as 0.4 mbar and corresponding change in current is from nA to μA range
Applications    
■ Highly responsive Oxygen gas sensor
