“The special feature of this fabric is that it can use both light energy and mechanical energy of human body movement. Of course, the study of “smart fabric†fully considers the safety issue, in addition to the safety of the fabric material itself, the current research process is also Concentrated in the low voltage range, it can be said to be harmless to the human body.
The paper shows that the raw material used in this smart fabric is a low-cost and low-quality polyester fiber, and a metal layer and a semiconductor coating are coated on the surface of the fiber to form a light energy. The solar cell power generation module, a power generation module capable of collecting weak mechanical energy during motion, the latter is actually a mechanical friction nano-generator.
These processed fibers are then woven with wool and woven together by a shuttle weaving technique to woven into this smart fabric, which is only 0.32 mm thick. Due to its material, this smart fabric is lighter and softer than ordinary clothes.

The shuttle is a shuttle with a small wheel installed in the chute. The ends of the looms chute are spring-loaded so that the shuttle can travel back and forth very quickly, which makes the weaving speed faster and can be woven wider than before. The cloth improves the weaving efficiency.
It is worth mentioning that the researchers also carried out various complicated series and parallel connection of the solar power module and the mechanical energy generator module of the smart fabric according to different electrical output requirements, and integrated into different parts of the human body clothing according to requirements. Studies have shown that in the case of sufficient light and stable conditions, a "smart fabric" with a length of 5 cm and a width of 4 cm, like the size of a girl's gloves, can maintain a voltage of about 5V, which can basically satisfy portable electronic devices, including electronic watches. Mobile phones and so on work without interruption.
At present, this smart fabric has not been tested for long-term durability, but after 500 curl tests by researchers, the performance of the fabric has not shown a decline.
"Smart fabric" for power generation experiments
“In addition to making wearable devices, this fabric can also be used to make larger self-powered everyday items, such as curtains and tents, and even integrated with other fiber-based functional devices, such as sensors,†said Fan Xing.
Smart fabrics are not new terms. The smart fabrics we mentioned at the earliest are generally made from fabrics that block electromagnetic radiation purchased in department stores and made from fabrics that can withstand radiation. In 2014, American fashion brand Ralph Lauren launched a smart sports t-shirt called "Polo Tech Shirt" at the tennis tournament to collect athletes' workout data on the spot.

On July 3, 2016, Google Inc. announced that it has launched the first smart clothing Levi's Commuter Trucker Jacket (hereinafter referred to as Levi's smart jacket) with Levi's, one of the world's largest apparel companies.
Levi's smart jacket
This smart outfit comes from a project called "Project Jacquard" intelligent loom. Google and Levi's are trying to introduce a real smart jacket in 2017 by reforming the existing loom technology. In the denim jacket we usually wear, the fabric woven by the intelligent loom can be a bridge between people and computers.
According to Levi's official website, Levi's smart jackets are first woven together with ordinary textile materials and conductive wires to form a new electronic interactive textile thread, and then the trousers are normally performed. These special wires are attached to a smart label on the jacket, which is equal to the connection center and control center of the information. Customers wearing Levi's smart jackets can control their mobile phones directly through their clothes, play music directly on the sleeves of their jackets, display maps, and more.
Levi's smart jacket for inductive body movements
Levi's smart jacket also has a matching app on the phone.
In addition, like the Apple Watch, Levi's smart jacket also has a matching app on the phone, and the commands corresponding to the user's control gestures can be preset and edited in advance. For example, after the customer rubs the surface of the clothes or puts a few times on the jacket, the silk thread of the jacket will transmit the information to the smart label of the control center, and respond to the corresponding control commands, such as mute the ringtone of the mobile phone or play the music of the mobile phone.
The latest Windows has multiple versions, including Basic, Home, and Ultimate. Windows has developed from a simple GUI to a typical operating system with its own file format and drivers, and has actually become the most user-friendly operating system. Windows has added the Multiple Desktops feature. This function allows users to use multiple desktop environments under the same operating system, that is, users can switch between different desktop environments according to their needs. It can be said that on the tablet platform, the Windows operating system has a good foundation.
