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.
