Fiber optic sensor for H2 gas detection in the presence of methane-based on Pd/WO3 low-coherence interferometric structure
Detecting explosive gases like methane has been a priority for industries such as gas and oil for a long time. The importance of improving the performance of gas sensors cannot be overstated. Gas sensors must be highly sensitive to detect even small amounts of gases. A recent study has explored the use of fiber optic sensors for H2 gas detection.
One of the most significant examples of fiber optics in offshore drilling is the use of Distributed Acoustic Sensing (DAS) technology. DAS technology uses fiber optic cables to detect vibrations and sound waves generated during the drilling process. This helps in identifying any potential problems that may arise during the drilling process.
The study found that using a thin amorphous WO3 covered with Pd film can create a high-sensitivity gas fiber optic sensor. The researchers utilized the interference phenomena and a specific configuration of the sensing structure to significantly increase the sensor’s sensitivity. The experiments resulted in a highly sensitive sensor that could operate at high temperatures up to 80°C.
These results are promising for creating high-performance sensors capable of operating in even the most challenging conditions. Fiber optic sensors have proven to be effective in detecting various gases, including hydrogen, methane, and carbon dioxide.
