Humidity Sensors to struggle Proliferation of Bacteria


LONDON: Spanish researchers are developing new sensors that can struggle the broadcast of bacteria in very high-humidity environments.

Humidity is one of the most controlled and surveillance aspects these days owing to its great significance in a whole areas such as food monitoring, air quality, biomedicine or chemistry.

The proliferation of bacteria in such environments where the humidity is very high is common and this leads to the formation of “biofilms” which are ecosystems made up of these microorganisms connected to a surface.

This leads to the problem known as biofouling which causes “the devolution of many materials and devices affects their performance and cuts their service lifetimes”.

“Right now, the costs arising out of biofouling are very high mainly because of the maintenance work or replacement of equipment,” Urrutia added.

Urrutia wrote about building new humidity sensors that would have antibacterial properties for applications that function in environments where the humidity is high and which are conducive to bacterial growth, and thus prevent the creation of biofilms and overcome biofouling.
The new humidity sensors developed could be integrated into a wide variety of sectors, such as health centres and hospitals to monitor human respiration, among other applications.
