Nokia has invested a lot in research work on wonder material Graphene. While most of us assume its most straightforward use in camera sensors and in developing new material for use in smartphone / Tablet body, there is more to Graphene than that it seems. Nokia‘s Research Center in Cambridge has developed a new humidity sensor based on Graphene oxide. The new sensor is claimed to be the fastest humidity sensor ever reported and is very thin (15 nm), transparent and flexible.

Researchers from Nokia‘s Research Center in Cambridge developed a new humidity sensor based on graphene oxide. The researchers say that the new sensor is ultra fast (the fastest humidity sensor ever reported, in fact), thanks to the graphene 2D structure and its superpermeability to water molecules. The sensor Nokia developed is thin (15 nm), transparent and flexible.

The sensor’s response and recovery time (the time to go from 10% to 90% of the high humidity value and vice versa) is less than 100 ms. The response rate is a function of the thickness of the GO, the thicker the film, the slower the sensor. Nokia has filed several patent applications regarding this work.

Humidity sensor are slowly making their way to smartphones. Many applications or smartphone profile changes can be triggered based on the analysis of humidity of the air. It can also cater to industries targeting user with relevant ads.

Thanks Kero for the Tip. Cheers!!
