Massachusetts Institute of Technology wearable toxic gas sensor was created by four researchers. The device functions by detecting toxic gases and warn users by talking to the smartphones or other wireless devices when danger is near.
Researchers, who have developed wearable toxic gas sensors, also hope to create badges that weigh less than an average credit card so the military can wear them easily in battlefields.
MIT toxic gas sensor updates a smartphone or other wireless devices when a conduction of the nanotubes occurs. It can help people who are exposed to toxic gases like a Sarin gas. The polymer breaks causing the insulation to disappear and makes the nanotubes touch one another forming a conduction. When there’s a conduction, the signal is directly sent to a smartphone or other wireless devices.
A team of four MIT researchers has developed a new wearable sensor that can detect toxic gases and talk to smartphones or other wireless devices to warn users when they are in danger.
Using these sensors, the researchers hope to design badges that weigh less than a credit card and can be easily worn by military personnel on the battlefield.
“Soldiers carry a lot of equipment already, and a lot of communication devices,” said Timothy Swager, Professor of Chemistry at MIT and lead author on a paper describing the sensors that was published in the Journal of the American Chemical Society. The paper’s co-authors are post-doc student Shinsuke Ishihara and PhD students Joseph Azzarelli and Markrete Krikorian.
“Soldiers have no wearable sensors to detect toxic gases. They use a variety of detectors, but they’re not the kind of thing you can carry around. Our sensors weigh less than a piece of paper,” Swager said.
