Do you know the evolution history from ancient underwear to solar underwear?

Underwear is very common. Wearing underwear to the streets is not news, but it is rare. If someone walks down the street wearing "solar underwear" that can generate electricity, I think the turn-back rate must be 100%.

Why do you say that?

First of all, let's talk about the history of underwear development.

In ancient times, underwear had a different name, called "obscene clothes", which means "light books, not solemn" It can be seen that the mentality of ancient people towards underwear is very different from that of modern people.

So how did China's underwear evolve into various trends and fashion styles? This will start with the history of underwear development in ancient China.

The Tang Dynasty pushed the ancient culture of China to a peak. In some TV dramas about the history of the Tang Dynasty, we can often see such a scene: "The ladies-in-waiting of the Tang Dynasty tied their skirts high to their chests, and then tied a wide belt with their shoulders at the lower part of their chests. The upper chest and back are exposed, covered with transparent gauze, and the end section is looming. " The "terminalia chebula" here refers to the underwear of the Tang Dynasty, which is similar to the semi-open skirt now. In the TV series "The Legend of Wu Mei Niang", Fan Bingbing presented the women's clothing in the Tang Dynasty very well, including the display of "terminalia chebula".

After the Tang Dynasty, with the development of Song, Yuan and Ming Dynasties, the shadow of modern underwear appeared. The two lapels are decorated with three lapels each, with a crotch on the shoulder and a belt on the crotch, and all lapels are tied with shoelaces at the waist side to form an obvious waist. It can also be seen from the side that ancient women have mastered the method of highlighting their figure.

In the Qing Dynasty, underwear reached a peak, with what we often say now, "tube top" and "Chinese-style chest covering", which have been used until now. Generally, the tube top is made into a diamond shape, with a belt on it and worn around the neck. Two belts are tied behind the waist, and the bottom is inverted triangle, covering the navel and reaching the lower abdomen. The material is mostly cotton silk, and the color is mostly red, which is what we call "red Chinese-style chest covering". In the TV series or movies of "Red Sorghum", there are many scenes of red Chinese-style chest covering. The profile shows that "Chinese-style corset" has been accepted and popularized by most women at that time. Of course, there is no lack of being loved by some men.

In the 1920s and 1930s, the "small vest" appeared again. It has a narrow shape, usually with a pair of buttons in front, which tightly wraps the chest and waist when worn, and absorbs some characteristics of the west, so it has become the current bra.

Modern underwear has many styles and materials. Natural materials are nylon, silk (protein fiber) and hemp. Artificial materials include nylon, lycra, spandex, viscose fiber, colored cotton and so on.

But have you ever heard of or seen underwear made of solar cells? It is estimated that many people, like the author, are hard to see at least in domestic underwear stores.

Next, let's talk about this "solar underwear".

American scientists call it "solar bikini" and Japanese scientists call it "photoelectric underwear". At present, there is no relevant news report in China, and American and Japanese designers have carried out creative designs.

No matter American or Japanese designers, their design principles and raw materials for "solar underwear" are similar. It relies on solar cells, sewing small cells together by telex to form underwear shape, and then using the photoelectric effect of solar energy to generate electricity to charge electronic products.

Seeing this, many people may have questions:

1. How long does it take to make such an underwear and how much does it cost?

It takes about 70 hours to sew a pair of underwear with ready-made materials, and such underwear is custom-made and naturally expensive. According to foreign news reports, such underwear is higher than 120 kg.

Second, where is this solar underwear suitable for application?

You can imagine a scene where a beautiful woman is lying on the beach, basking in the sun, electrifying her underwear, listening to MP3, playing with her mobile phone and Ipad, and no longer worrying about the lack of electricity and nowhere to charge her electronic products. If a built-in cooler is installed on underwear, and the cooler is powered by absorbed solar energy, it must feel good to wear underwear with cooling function!

Third, what is the safety?

Because underwear originally used less materials, even power generation can only serve as a small charger. Generally, the voltage is about 5V, which the human body can't feel and there is no danger of electric shock.

Having said so much, the effect is so attractive. Why is such underwear really not on the market? Designers define it as a concept product at present, and there are still many technologies to be improved in order to popularize it in the future, such as the replacement of solar underwear and the problem of putting a jacket on underwear to generate electricity.

Once popularized in the future, I think it will be very eye-catching, eye-catching, energy-saving and environmentally friendly fashion clothes!
