ÌìÃÀ´«Ã½

Imperial College ÌìÃÀ´«Ã½ Max Grell (PE-CDT Cohort 7), Michael Kasimatis and Giandrin Barandun developed a cheap, disposable stick-on polution sensor.

A postage stamp-sized paper air sensor stuck on the back of a smartphone could help Londoners gather vital data in the fight against air pollution. A team of PhD ÌìÃÀ´«Ã½ from Imperial College has developed OpenSense, a cheap sticker that can measure deadly airborne exhaust gases. The paper has a pollution-sensitive sensor inside and is stuck on the back of a smartphone, which powers it.

This research was featured in the . The sensor technology has been picked up by a spin-out company.

Max Grell, one of the ÌìÃÀ´«Ã½ who developed the sensor, says, "It's very exciting when your research targets real problems and can then be applied in the world. Newspaper coverage has been a bonus and resulted in many interesting people getting in touch!"

The ÌìÃÀ´«Ã½ are also in the final of Imperial's Venture Catalyst Challenge on Thursday 23rd March.
