The path of clothes and food crossed once again. And I’m not talking about chocolate clothes like in the photo below, but clothes made from food bacteria. Discover the “living clothes” here at Eat Innovation.
The researchers accidentally discovered that bacteria Bacillus subtilus naturally swell or shrink, according to the humidity to which they are subjected. These bacteria are known to be key players in the production of natto, fermented soybeans, much appreciated in Japanese cuisine.

In the prototype called “Second Skin“, the team produced clothes that naturally open slits to allow air to pass through and eliminate sweat, refreshing the person during sports practice. Human body sheds sweat to keep body temperature under control, but normal clothing is a barrier to this process, unlike living clothing.
The fabric consists of three layers, the outer layers being impregnated with bacteria. The crevices cut in the material were arranged according to human body heat maps. Thus, they open up exactly in the parts that most need to be cooled during the exercises. When the skin is dry, the cracks are closed. With the heat and humidity of the body, the bacteria swell and the cracks open.
Bacterial multiplication is done in the laboratory and then printed on fabric using a biological printer. An advantage of living clothing is that it does not require energy and consumes few resources in production. While, for example, the production of electronic motors is done by assembling several parts, the bacterial cells can reproduce themselves and reach up to 10 billion in a single evening.
Other applications of these living textiles are already underway, such as a lamp that opens when the light is on. The potential is huge.
If I had this living fabric, I would make a curtain that opens or closes according to the sun incident on the window. And you, if you had this fabric in your hands, what would you apply it to?

The texts I wrote and didn’t publish before, I’m publishing now with some additional content, but always preserving the original. A lot has happened in the last few years that have changed the course of my life and this blog. To learn more about this long absence, click here.
