in the future, your clothes will warn you of dangerous gases

We want to know more than ever what we are breathing.
Now is the era of air purifiers, check the weather app to see the air quality, and shamelessly wear masks to protect yourself from pollution and particles.
But what if your clothes change color and inform you of dangerous breathing conditions?
Nanotech scientists at the University of taftz, Massachusetts, have developed a simple technology that can do this.
\"You can have the certified inspector tell you that your water, environment or food is not good, but it would be great if people make those judgments themselves,\" Sameer Sonkusale, A mechanical and computer engineer in charge of the university\'s Nano Lab told the Daily Beast.
\"I always think that knowledge is power.
I think technology has improved a lot. There are many innovations that can be achieved with simple basic things.
\"Sonkusale\'s labs have been working on a variety of low-cost portable sensing platforms that allow ordinary people to access data from the world around them, otherwise they will not be able to access it. The color-
The change technology relies on different dyes that naturally change color when they are exposed to specific gases.
For example, brothy phenol blue dye reacts to ammonia, and a red dye reacts to hydrogen chloride --
Two common gases in cleaning supplies and fertilizers.
\"With this, we realize that we can provide a way for people to see environmental pollution,\" he said . \".
Biggest challenges to natural gas development
Sensing textiles are not actually transferring dyes to fabrics;
This is to figure out how to keep the dye in place and make them strong enough to withstand regular wear and washing.
Initially, the team tried to chemically treat the dyes to lock them in place, but they found that the technique made them less sensitive.
So they created one.
Keep the dye sensitive and capture it in the fabric thread to make the fabric dye durable.
Chemical treatment opens the fibers of the fabric
Separation of microstructure in threads
And allow the dye to enter every Nano. Corner and Gap.
They then added a porous thin polymer film (
Allow gas to enter)
But put everything in place.
The trick, added Sonkusale, is that the polymer film cannot be too thick or hard to make the thread no longer look like a fabric.
Once the problem is solved, the technology is easy to implement in the end, and the cost is low, he said.
\"Surprisingly, this approach is quite simple.
\"This is something that should have been done some time ago,\" Sonkusale said . \".
In practice, stingy-
Detecting color patches can be sewn on a variety of different types of clothing and used as a \"canary in a coal mine\" to alert people to nearby gas.
People can use them at home or in the car
They can also serve as early warning systems for work with potentially hazardous chemicals, such as chemical laboratories or construction sites.
Because the polymer coating is very effective, the dye is even able to detect gas under water.
Sonkusale and his team have even developed a mobile app that allows users to compare images of fabrics over time in order to detect even minor color changes.
So far, people are very interested in further developing this technology (
Especially as a handheld sensor)
By putting the dye on the portable card.
\"You don\'t always need to put it on the fabric-\" Sonkusale said --\"
The detector can be cleaned and reused over multiple cycles, or simply and quickly usedtime throw-aways.
He said that no matter how they are used in the end, they have the potential to give people more control over their health and their environment.
\"The more we know, the more capable we are,\" he said . \".
