Three trends in the future of smart wear

 

First: Medicalization

Health is the first scenario for smart wearable devices and it will further penetrate the daily life of users in the subsequent technological development process.

 

For healthy consumers, it can play a role in monitoring, warning, and prevention.

 

Consumers with sub-healthy bodies can get a use experience that is close to normal people through smart wearable devices.

 

Of course, the above consumers may also obtain some kind of "super-sensory" and "super-human" experience through smart wearable devices.

 

Second: Fashion

With the further development of technology and the further improvement of consumers' aesthetics, the boundary between fashion and technology will be further blurred.

 

In the field of science and technology, in order to maximize value, it often deliberately creates and amplifies some kind of "sensory" experience. In addition, the fashion of technology products can eliminate the guard of users and the discrimination of onlookers; this makes technology products more and more. The more refined.

 

Although it is a major trend that technology products become fashionable, brand tonality is not so easy to eliminate, just like Xiaomi's easy entry into the smart jewelry field will only be thankless.

 

Third: Aging

For the aging of the population, a global problem that cannot be avoided in the world, an aging design that is friendly to the elderly is not only in the field of smart wear but also a reality that needs to be faced in manufacturing, design, and creativity.

 

The key to the aging design is to provide more help to the elderly without causing a


cognitive burden.

Japan announced that it will ban the sale of fuel vehicles. Is the era of new energy vehicles coming?

 


Recently, according to overseas media reports, Japan’s Ministry of Economy, Trade, and The industry have initiated adjustments in the direction of stopping sales of new gasoline vehicles in Japan in the mid-2030s. In the future, all new vehicle sales in Japan will be converted to hybrid and pure electric models.

 

The Ministry of Economy, Trade, and Industry is expected to announce the above guidelines after a meeting with stakeholders in the automotive industry on December 10. The meeting will discuss specific topics such as stopping the sale of new gasoline vehicles and formulating a framework for popularizing hybrid and pure electric vehicles.

 

It is reported that the Japanese government has set a goal to reduce the proportion of gasoline vehicles in new car sales to 30% to 50% within 30 years, but it has not yet stated when sales will be banned. This series of measures are all aimed at achieving the government goal of zero greenhouse gas emissions by 2050. This means that Tokyo’s "burn ban" target is five years earlier than entire Japan.

 

Data shows that the number of new cars (passenger cars) sold in Japan in 2019 was 4.3 million. Among them, about 60% (2.61 million vehicles) are gasoline and diesel vehicles. The remaining 30% are hybrid vehicles, while pure electric vehicles, which are more effective in global warming, are only about 0.5%. This is because in the Japanese market there are still problems related to the maintenance of pure electric vehicle charging piles that need to be solved. On the other hand, Japanese car companies such as Toyota mainly introduce hybrid models to the market as their main environmentally-friendly models. , The proportion of pure electric vehicles is relatively small.

 

Regarding the issue of the ban on the sale of fuel vehicles, not only Tokyo but the United Kingdom also plans to ban fuel vehicles in advance by 2030. Recently, the British Prime Minister publicly announced that he plans to advance the original ban on the sale of fuel vehicles by 10 years, starting from 2030. At the same time, France, Israel, Spain, and other countries have announced plans to phase out fuel vehicles between 2030 and 2040.

 

  As the timetable for the ban on the sale of fuel vehicles in various countries around the world has been finalized one after another, major auto companies have also transformed their deployment of new energy vehicles. Volvo and Fiat have already stopped selling fuel vehicles in 2019. Leading car companies such as Honda and Volkswagen have also put plans to stop selling fuel vehicles on their agendas, and successively announced their own new energy plans.

 

It is worth mentioning that with regard to the ban on the sale of fuel vehicles, China’s Hainan Province will also stop selling fuel vehicles in 2030. Related organizations predict that China will achieve a complete withdrawal of traditional fuel vehicles before 2050, and complete the goal of banning the sale of fuel-based private cars around 2030. Although China is still far away from the launch of the "Fire Banning Timetable", according to official guidance and private research, the period for China to achieve this goal should be after 2035 and before 2050.

Plastics makers plot the future of the car

 


With the rapid development of the automotive industry, especially the rapid development of new energy vehicles (including hybrid, pure electric, and hydrogen energy) in recent years, the automotive industry has demand for lightweight, integrated, miniaturized, and electrified auto parts Also increasing day by day.

 

Plastic is an indispensable material in the automotive field and its process and performance requirements are increasingly becoming everyone's attention. At the same time, higher requirements are also placed on the R&D capabilities and rapid response capabilities of the material suppliers.

 

Miniaturization of turbocharged engines requires high-temperature resistance of plastic materials

 

The latest development trend of internal combustion engines is miniaturization and intake supercharging (that is, turbocharged high). The huge benefits brought by these two technologies are a significant reduction in fuel consumption, an increase in engine power, and a reduction in overall engine mass. For example, The two-piece structure design of the previous engine intake manifold has been changed to an intake manifold with an integrated intercooler.

 

This design puts forward higher requirements for the high-temperature resistance and high strength of the material. It needs to withstand high temperatures of 190°C and 230°C for a long time and has excellent strength.

 

 

Electrification requires low precipitation and neutrality of plastic materials

 

As more sensors have been placed in various positions of the vehicle, the integration of electrification continues to improve, and the requirements for materials of this electrified equipment are more stringent than before, such as low precipitation (not to block the oil circuit of the capillary structure), Electrically neutral (not to cause a short the circuit in the circuit), materials need to meet the requirements of relevant laws and regulations (not to contain prohibited substances), etc.

 

Polyamide (nylon) materials are widely used in the automotive industry for their excellent mechanical strength and long-term heat resistance. Its heat resistance is related to the heat stabilizer. Common heat-resistant stabilizers include metal salts (such as copper iodide/copper halide, metal stearate, etc.) and aromatic amines (such as aniline substances, etc.). With the increasing awareness of environmental protection, some of these heat-resistant stabilizers have been banned by relevant regulations due to their side effects. For example, the latest EU regulations strictly control N, N'-diphenyl-p-phenylenediamine (DPPD) substances .

 

 

New energy vehicle requirements for flame retardant properties of plastic materials

 

With the rapid development of new energy vehicles (including hybrid, pure electric, and hydrogen energy), related standards for parts and materials in this field are also rapidly refined, for example, requirements for different flame retardant systems, flame retardant systems Cover roughly 5 types, namely: halogen flame retardant, nitrogen flame retardant, inorganic flame retardant, phosphorus flame retardant and nitrogen-phosphorus synergistic flame retardant; among them, the flame the retardant mechanism is divided into gas phase flame retardant and corrosive" Carbonized" flame retardant, such as red phosphorus, inorganic flame retardant, etc.

 

Different flame-retardant systems have different flame-retardant effects, and at the same time have obvious changes in the physical properties of the material (such as density, rigidity, and toughness). So how to choose a flame-retardant system to match the flame-retardant effect and mechanical strength requirements of the components is a very complicated problem that must be solved.

 

New energy vehicle requirements for thermal aging stability of materials

 

In the high-voltage parts of new energy vehicles, according to regulatory requirements, bright orange materials are required to mark the relevant parts as high-voltage areas. The components in the high-voltage area tend to continue to heat up after the current is connected. Therefore, most vehicle manufacturers also put forward related thermal aging stability requirements for orange materials. For example, after 90+1000h thermal aging, the color change of RAL2003 shall not exceed Darker orange such as RAL2008, RAL2009.

 

In the future automotive industry, lightweight and weight reduction, electrification, high transmission efficiency and miniaturization of turbocharged engines will surely become a whole and become the indicators for the development and verification of most highly integrated auto parts. . Material manufacturers also need to actively respond to the market and improve material performance to meet the new requirements of the automotive industry.

Electric cars will become the mainstream of future cars.

 


The process of human industrialization has gone through the steam age, the internal combustion engine age, and the electrification age. It is still in the second half of the electrification age. The ultimate goal is the full electrification of society. Trends: First, in railway transportation, electric locomotives replaced internal combustion engines; then in the field of unmanned aerial vehicles, electric motors replaced internal combustion engines; then in the field of automobiles, but also in the field of ships; the field of manned aviation was affected by energy density and The specific driving mode restrictions may not be fully electrified.

 

In the past, model airplanes were actuated by diesel engines, which required operators to have considerable skills and experience to overcome extreme complexity and difficulty. Therefore, it was still difficult to miniaturize, and therefore, it was difficult to realize airplane models. Mass popularization; and since the emergence of electric multi-rotor drones, it has become quite simple. Why? Because the flight control computer can adjust the parameters of each motor hundreds of times per second, while on the internal combustion engine, drones have quickly become a major industry.

 

The all-electric propulsion of ships is also a trend. First of all, starting from the warship, the 055 initial big drive gradually adopts all-electric propulsion. The benefits are: simplification of the complex mechanical transmission and speed change mechanism; greatly changed noise; more flexible power adjustment, and so on.

 

From the perspective of automobiles, the advantages of electric vehicles over traditional gasoline vehicles are still quite obvious, and they will become more and more strengthened:

 

1) The mechanical structure is greatly simplified, without the need for complicated gearboxes and transmission mechanisms. The complicated differential locks and other mechanical and electronic devices on the past off-road vehicles will not be needed in the future. In the future, it will be easily solved by using hub motors, and even the car can turn around in place

 

2) Simplified maintenance, no chemical combustion process, no complicated mechanical structure, natural maintenance is much simpler;

 

3) More environmentally friendly: Some voices on this issue are controversial. They believe that electric vehicles are not environmentally friendly in terms of the full life cycle of electric vehicles. One point of view is that the electricity from the grid used by electric vehicles is mainly to replace coal power; the other point of view is lithium battery production. The environmental problems that arise when it is scrapped are also great.

 

I think these two views are static views: in 2017, coal power accounted for only 60%, and the conversion of wind power in the future will continue to reduce the cost of photovoltaics, and the proportion of coal power will continue to decline; and the production of lithium batteries will be scrapped. Industrial development and technological progress will always be properly resolved. The exhaust emissions of gasoline trucks are the most important source of PM2.5, and this problem is unsolvable.

About medical, What kind of wearable devices do we need

 According to the market research organization Transparency Market Research, medical care is the most promising application field for wearable devices. Medical and health management products have become the mainstream of the market, and wearable devices such as bracelets and watches have appeared.

Because both sports health and medical monitoring equipment are related to health, and human health is the most basic need.

In terms of product functions, wearable devices currently have multiple functions such as health monitoring, medical treatment, sports, entertainment, office, learning, and positioning. Compared with the 15 monitoring categories abroad, there are 13 categories in the domestic category distribution, with sports taking the top spot, accounting for 32.9% of the market share, followed by sleep and body temperature monitoring. Which shows the uneven distribution of products, too much, There is too little situation. It also reflects from the side that the current medical wearable products are still in the primary application stage and have not been well known and used by the public. Smart wearable products have not yet deeply served medical care.



Medical wearable equipment type

If the main purpose of medical wearable equipment is health. It can be roughly divided into sports health and patient monitoring.

Sports health category, the main function is to monitor the amount of exercise, calories burned, heart rate, sleep, mainly wearable small devices such as bracelets, watches, smart shoes, patches. For example, Xiaomi bracelet, Lexin bracelet, Gudong bracelet, Huawei TalkBand series bracelet, Apple watch, Huawei watch, etc.

Patient monitoring, the main function is to help patients with chronic diseases monitor blood pressure, blood sugar, brain electricity, mainly including blood pressure monitors, physiological monitors, and other products.

As a user, why should I choose a wearable device?

Because I need to exercise to enhance my physical fitness, it is best to have a device that can accurately monitor my body data and help me provide physical fitness. Because I am sick and have chronic diseases. I need convenient and easy-to-use devices Equipment to help me monitor my physical condition, instead of running back and forth to the hospital.

Medical wearable devices have greatly promoted the development of mobile medicine while providing consumers with a convenient, fast, and fresh experience, which can protect consumers’ health. However, medical wearable devices also have problems such as market chaos and serious product homogeneity. Which urgently needs to be regulated by unified industry standards. In January 2015, the U.S. Food and Drug Administration (referred to as FDA) issued two draft guidance on Internet Elizabeth. The FDA detailed the criteria for determining the low-risk platform medical. And health products and made basic recommendations for the risk assessment of the third wave of medical accessories. At present, there is no standard in this regard in China. If standards for medical wearable devices similar to those in the United States can be issued as soon as possible, this market will be greatly regulated, thereby promoting the faster and healthier development of mobile medicine.

At the same time, for these medical wearable companies and related mobile medical platforms. They must not only focus on products but also provide corresponding supporting services. Only when the services are truly implemented can user stickiness be increased and users have long-term use. The desire to meet their medical needs well.
