4, wearable devices Google glasses
Google Glass is actually a head-mounted display system that must be used with a smartphone. Microphones and earphones are integrated on the tiny Google glasses, and a miniature camera is built in the left front, which allows the wearer to take pictures, send and receive information, and implement other functions through voice commands. The batteries required for the glasses are also embedded in the frames, which are very simple and modern. What is even more commendable is that it weighs only a few tens of grams and is a smart phone that can be placed on the bridge of the nose. If the wearer says "OK, Glass" to Google Glass, a menu appears on the small screen above the wearer's right eye, displaying multiple icons that let you click on the icon with a voice command. Of course, the wearer can also manually control the Google glasses through the touchpad on the arm of the glasses, and even some simple manipulations can be made by nodding and shaking his head. Google’s promotional video portrays scenes where a man walks on the streets of New York City, chats with friends, looks at maps, and sometimes stops to take pictures. At dusk, the man faced a sunset and video chat with a female friend. And all this is done through Google's eyes, this is the expansion of reality glasses.

5, smart fashion clothing
At CES 2014, the Dutch showcased a fashion that can be transparent based on changes in human emotions – InTImacy 2.0. It uses leather and thin foil-like smart foils, coupled with electronics, LED lighting and other technologies. When people wear this dress, people's emotional changes such as excitement, shame, etc. will change the color of the clothes. Give people a glimpse of beauty. InTImacy means "intimate", which can change the transparency of the sheet according to people's behavior and distance, and the heartbeat will speed up. InTImacy 2.0 will become more transparent, wearable and sexy.
Wearable smart device market scale prospects
According to the "2013 China Wearable Device Market Research Report" released by Ai Media Consulting, it is estimated that by 2015, the market for wearable devices in the Chinese market will exceed 10 billion yuan, reaching 11.49 billion yuan.
According to relevant data, in 2014, the global shipment of wearable smart terminals will exceed 100 million units, and by 2018 it may exceed 300 million units. The Credit Suisse Group's forecast report believes that the market size of global wearable devices is expected to reach 30 billion to 50 billion US dollars in the next two to three years. However, some market participants are worried that the prospect of wearing equipment is not clear now, and the price/performance ratio of many products is low. The swarming madness will become a short-lived or another new continent, and it is still to be tested by the market.

Phenolic Cotton Cloth Laminated Sheet is a laminated material made by hot pressing of cotton cloths impregnated with a thermosetting phenol-formaldehyde-based binder.
Due to the use of cotton cloths, the phenolic cotton cloth mixture has high compression strength and increased resilience, favorably lends itself to machining by drilling, cutting and forging. That is why it the phenolic epoxy resin cotton cloth laminated sheets are widely used to make parts loaded with reversed electrical and mechanical stresses or working under friction (bushings, cams, etc.).
The textolite or phenolic cotton cloth sheets are used as insulating material for work in transformer oil and in the air at normal relative humidity of the environment and at 50 Hz of frequency.
Long-term allowable working temperature: -65°C to +105°С.
Phenolic cloth laminated sheet is made of cotton cloth impregnated with phenol resin, baked and hot pressed. It has high mechanical properties, oil resistance and certain dielectric properties. The heat resistance level is E level.
