When someone told me that towels can also change color intelligently!

My first reaction was: I can cheat!  

People who play with various intelligent hardware for a long time will always have various circuits in mind.

The towel is so soft and often soaked in water. How can it realize the circuit function?

So, with all kinds of questions, we launched the experience exploration of smart towels.

The official said: Xinjiang long staple cotton, 100% natural plant extract, soft, environmentally friendly, no odor, formaldehyde, heavy metals, carcinogens, no additives.

Experience said: soft colors, clear printing patterns, even loops, neat seam edges, exquisite materials, and perfect workmanship,

It feels soft, fluffy and elastic in the hand, and sticks to the face, giving people a feeling of being close to the skin and breathable,

It has no irritating odor.

Officially: 0 discoloration, 0 hair loss.

Experience said: put the towel in a transparent water cup and let it stand for a while, slightly fade but not affect the use; Rub and stretch the towel back and forth with your hands, and the wool really falls off.

Officially, water absorption=10 × its own weight.

Experience said: self weight=102.56G, weight after water absorption=495.56G, water absorption=495.56G-102.56G=393G,

Water absorption=3.83 × its own weight (experimental premise: the towel is full of water and does not drip),

Experiments have proved that the water storage capacity is close to 4 times, and the official claim of 10 times of water storage capacity is obviously exaggerated. It is estimated that it can only be realized without considering the effect of gravity.

The official said: intelligent sensing, color change warning, pollution degree gradually deepened with the color

Experience: from top to bottom, sweat, olive oil, cola, cosmetics,

When pollutants touch the blue sensing area slightly, they change color rapidly. With the change of turbidity and pollution amount of pollutants, the blue sensing area will also change color in varying degrees.

The experiment proves that the blue sensing zone is very sensitive to pollutants. The pollution level changes with the color at a glance.

Officially, water absorption rate=0.1S.

Experience said: because the dry towel is very light, it is inserted into the water cup with a little force, instead of falling into the water cup naturally by gravity,

The water absorption process is a little slow, rather than as fast as a sponge, and the water absorption speed is obviously more than 0.1S.

Officially, it is reversible and recyclable.

Experience said: Use a cotton swab dipped with hand sanitizer to gently touch the contaminated area, instantly restore the original blue appearance, and can be recycled after cleaning.

The experiment proves that the sensitivity of the contaminated area to the cleaning solution is very high. It can restore its original color at one touch without any trace. There is no need to scrub the towel back and forth. It can be reused after simple cleaning

Overall:

This is a kind of smart towel with soft hand, strong affinity to the skin, good water absorption, intelligent reminder of pollution, sensitive sensing of color change area, and recyclable.

However, as a lazy person, I pay more attention to:

Since the vegetable towel can remind pollution like a chameleon, why can't we further realize self-cleaning?

While sensing pollution, it also has the ability to quickly decontaminate, killing two birds with one stone!

And when the towel is scrapped, the blue sensing area directly becomes black and can not be restored, reminding people that it is time to change the towel.

It seems that there is still room for progress!
