These sensors can detect hazardous chemicals

Some scientists from the Massachusetts Institute of Technology (MIT) has recently developed an impressive sensor that serves to protect us from a variety of things ranging from bombs to expired foods. Mentioned, the sensor is very simple. The sensor was modified of the NFC chip to detect the presence of specific gases with the help of nanotub carbon.

The functionality of the sensor is very interesting. Although the team of chemists who developed this technology to explore all sorts of different use for it, this sensor will be a very useful tool for checking the packages of food.

These objects can tell us whether a food has expired just by waving our smartphones. To see test these sensors detect the chemical substances with a smartphone, you can see the video below:

"The beauty of these sensors is that they are very cheap. You pair them up and let them sit in there and then you read. There should be no wires. No need power," said Professor Timothy Swager, an MIT scientist, through the official renowned university website.

"You can be very imaginative about what you want to do with technology like this," he continued. The MIT team that discovered this sensor has filed a patent on the technology. They are also trying to improve the work of this sensor with Bluetooth, so it can increase its reach.

In fact, scientists think they will be able to integrate it with the badge so that the employees who work in hazardous areas may get a warning if there is the presence of a hazardous gas around them. *** [EKA | FROM VARIOUS SOURCES | GIZMAG]
