Researchers from Nanjing University in China and Fukui University in Japan (hereafter referred to as the "joint team") have collaborated on the development of a high-tech, wearable fabric that generates energy through body movement. They published their findings in the peer-reviewed journal Nanoenergy.
The Joint Team utilized the principle of friction-induced electricity to generate friction electricity. Friction-induced electricity is a phenomenon called friction-induced electricity (or the phenomenon in which two different objects are rubbed against each other so that one is positively charged and the other is negatively charged) that involves the use of friction to electrify two different objects.
In practice, frictional electricity is created by rubbing two materials together, thereby enhancing the contact between their surfaces. For example, this frictional electricity may occur when you thread a hair through your hair.
Based on this phenomenon, a composite material called a "friction electric nanogenerator" (also known as a TENG) has been developed that can be used to convert mechanical motion into electrical energy. Due to its small size, Teng can drive electronic devices through the movement of the body. The friction layer acquires an electrical charge as a result of the body's mechanical movements, such as when walking or running. This process converts mechanical energy into electrical energy, which is then used to charge the electronic device.
The friction electric nanogenerator (known as EF-TENG) all-fiber composite layer can therefore be used in the clothing manufacturing process, where the composite layer is easily incorporated into ordinary fabric to create clothing that generates electricity.
The friction electric nanogenerator material is not an entirely new technology. The material was first successfully developed in 2012 by academician Wang Zhonglin of the Chinese Academy of Sciences, and can collect and utilize electricity generated by friction and static electricity from shaking hands, walking, and tides.
However, traditional friction electric nanogenerator materials have some unpleasant properties, such as poor breathability. In addition, they are not very efficient at generating and delivering electricity.
To address these problems, the joint team improved the performance of friction electric nanogenerator materials based on related technical research by using silver nanowires as electrodes and electrospun polystyrene nanofibers as a charge storage layer, forming breathable antimicrobial electrodes and electrostatic induction-enhancing layers to achieve better performance and improved breathability.
In addition, the charge accumulated on the surface of the original friction electric nanogenerator material is slowly lost or dissipated, which reduces output performance and surface charge density. Stabilization of the surface charge density was achieved by the joint team's improvement with the addition of a polystyrene membrane.
A full-fiber composite nanogenerator made of electrostatically spun polyvinylidene fluoride/nylon, silver nanowires, and polystyrene can be easily integrated into regular clothing, allowing it to charge small electronic devices through daily movement. The team demonstrated the performance of their new high-tech textile by powering 126 LEDs. Nonetheless, the device still lacks sufficient output to charge devices that need more power.
Dr. Hiroaki Sakamoto, one of the authors of the joint team's paper, said that because the new material formed in this study is softer and more breathable, its material properties mean that future possibilities for harvesting static electricity from clothing, when applied widely, will have a enormous potential.

These changes lead to changes in the molecular structure of the **** yoke system. In materials science, there is a saying that the structure determines the nature. Changes in the *** yoke system of color-changing materials are manifested in the macroscopic changes in the color of the material. According to the different external stimuli, intelligent color-changing materials can be divided into photochromic (light source stimulation) textile materials, thermochromic (external environmental temperature stimulation) textile materials.
_With this kind of intelligent color-changing material, we will have a more comfortable wearing experience. At present, this smart textile material researched by scientists is mainly a color change. In addition to this, there are still some problems with this material that has been researched so far. These problems are mainly focused on the performance of color change. I believe that with the further progress of time, the relevant scientists will conduct further research. We will develop multifunctional smart textile materials. Multifunctional smart textile materials, too, will inevitably be the focus of the entire research and an important area of research. Smart textile materials also have very high value applications in the future. The market demand for smart textile materials, will also be particularly large. Smart textile materials, is a material that can improve people's wearing experience.
What exactly does Samsung's smart clothes look like?
With the development of smart wear, smart clothing, as one of the important branches, has been favored by more and more people in recent years.
This is inextricably linked to its importance, as China often says, "clothing, food, housing and transportation", of which clothing is in the first place, clothing has become indispensable in today's things.
From Nike, Adidas, UnderArmour and other sportswear leaders, to Apple, Google and Intel and other tech giants, all announced that they are investing in research and development of smart clothes.
Some time ago, Google and Levi's teamed up to develop a wearable device equipped with a jacket, which is woven into the "electronic interactive fiber material", allowing cycling enthusiasts do not have to take out their cell phones, but through the clothes directly control their own cell phones, the clothes themselves can also provide users with many functions, such as from the The jacket itself also offers many features, such as the ability to play music and display maps directly from the sleeves of the jacket.
In addition to Google, smart clothing is already being used in a number of areas, such as in the military and in health care. To combat hot weather, some smart clothing can even keep you warm in winter and cool in summer. But a recent patent granted to Samsung is also related to smart clothes, and surprisingly the clothes can also charge electronic devices.
Recently, South Korea's Samsung Electronics Co. was reportedly awarded a patent for "smart clothes" that can be used to charge electronic devices.
According to the patent's description, the suit would collect energy from arm movements into a special battery. So the suit will be fitted with the necessary sensors and processors to collect data on human activity.
As you can see from the picture, multiple sensors are distributed all over the garment, not just the clothes, but the patented system can be applied to jackets, pants, hats, gloves, and shoes for any desired garment.
If it's possible to have the device connected to the clothing, then the energy generated through the clothing and movement could charge the device. However, the exact capacity of the battery is not yet known, but the patent application states that it is not large. But as a necessity of life, if it has other powerful additional attributes beyond meeting one's basic needs, this is undoubtedly something that people are happy to see. Especially with the popularity of smart phones, and the battery technology is slow to progress, this time a clothing that can charge the phone, I believe many people will like.
It is not yet known whether the clothes are washable. Samsung actually filed a patent for this in South Korea last year, and it may be ripe for the picking in terms of technology, so maybe people will see this product soon.
In fact, regarding smart clothes, Samsung introduced the concept of "SmartSuit" to the public at CES 2016, and at CES, Samsung also showed off its BodyCompass 2.0 shirts, which are equipped with electrocardiogram and electromyogram sensors, Weltsmartbel belt and other "SmartSuit" products. These clothes look no different from normal clothes in appearance, but these SmartSuit smart clothes can realize real-time monitoring of heart rate, exercise steps, body fat and other body data, but also with the application for people to make reasonable suggestions.
It is obvious that intelligence has become a trend in the development of clothing, smart clothing to meet the contemporary young people for the trend of fantasy, in addition to bring more convenience to people, more traditional clothing industry has brought a new innovative power. In the future development, is about to usher in a new round of growth.
