Now wearable devices can be roughly divided into four categories.

Smart phone school-representative figures: GalaxyGear, smart watches

As a functional supplement of mobile devices, it must be used with smart phones and other devices.

Comprehensive intelligent school-representative: GoogleGlass

Although these devices also need to be connected to mobile phones, they are more powerful and independent.

Institute of Human Health Testing-Representative: JawboneUp and Nike+ series products.

How many steps did you take today? How was your sleep? How many calories are consumed in a basketball game? This is the characteristic of these devices.

School of human health intervention-representative figures: OrCam, bebionic3 bionic hand, and each neck ring.

OrCam is a wearable device that allows visually impaired people to read and move freely. bebionic3 is a bionic hand worn on disabled people. The function of such products is to directly intervene in the human body and achieve the effect of improving the current situation of the human body.

Mystery school -iwatch

In fact, iwatch is not necessarily a watch, but probably an Apple TV?

Smart bracelet, smart watch, smart glasses, Bluetooth headset, TWS headset, etc. It is the mainstream of the smart wearable device market at present. They have portable characteristics and multifunctional interactive experience, and support real-time transmission or data synchronization with mobile phones through Bluetooth connection or APP.

In the test of smart wearable devices, the maximum current that the elastic micro-needle module can pass can reach 50A. When the current is transmitted, it circulates in the same substance and has a stable connection function. Wearable devices are small in size, and the corresponding connectors are also developing towards small spacing. The desirable range of elastic microneedle module can be kept between 0. 15mm-0.4mm with good adaptability, stable conduction and transmission, which can make the test of smart wearable devices stable.

What wearable smart devices are there?

There are mainly the following types: smart watches, smart bracelets, smart glasses, VR headsets, smart helmets and smart sports shoes.

Smart watches and smart bracelets mainly include Huawei, Xiaomi, OPPO, VIVO and so on. Huawei also has its own smart glasses products, Iqiyi has released smart VR wear, and Nike has smart sports shoes.

Development prospect of smart wearable devices;

With the outbreak of 20 14 smart wearable devices, the official listing of 2065 438+05 apple watch, and the release of new products such as HuaweiWatch, HTC's Grip fitness bracelet and virtual reality headset Vive, smart wearable products will become more fashionable, intelligent and diversified.

The general trend of consumer electronics industry reform, based on the new economic structure under the background of western development, will build a global display and trading service platform for the whole consumer electronics industry chain, help global elites break the time and space boundaries, realize efficient and convenient exchanges and cooperation, promote the deep integration of consumer electronics industry with advanced technologies such as 5G, big data, cloud computing and artificial intelligence, and promote the integration and innovation of global industrial resources.

The industrial chain of the wearable device market mainly includes hardware, industrial applications, social platforms, operational services, big data, cloud computing and other links. At present, the wearable device industry is not mature enough. The products of different manufacturers are independent and closed, lacking cooperation, and the data cannot be effectively enjoyed. At the same time, each wearable device develops its own application and data service platform.

What products does smart wear include?

At present, wearable smart devices include smart watches, smart bracelets, smart glasses, VR headsets, smart helmets and smart sports shoes.

At present, the smart glasses market mainly combines smart audio with the shape of glasses, so that it has two functions, which can be used for fashion decoration and open audio experience. However, this is only the beginning of manufacturers in the direction of smart glasses. With the continuous development of technology, smart audio glasses will be gradually linked with visual technology to realize some functions of AR augmented reality and provide richer applications.

Black technology eSIM smart watch can measure body fat, do you believe it?

Smart watches have added more and more functions, such as eSIM, GPS, sleep monitoring, heart rate monitoring, blood oxygen monitoring and so on.

In daily life, our common devices for detecting body fat are body fat scale and sebum forceps.

Body fat scale is a weighing instrument that can measure fat, moisture and so on besides weight. The principle of human body fat scale is that muscle contains more water such as blood and can conduct electricity, while fat is not. Because the channel conductor of current in the body is muscle, the weight of muscle can be known from the difficulty of current passing, so as to judge the proportion of muscle in the weight.

Sebum forceps are instruments for detecting human body fat. Its advantages are convenient to carry and simple to use, but it is necessary to calculate body fat according to the formula.

Can I measure body fat with a smart watch?

The technical principle of measuring body fat by smart watch is similar to that of human body fat scale, and the wearer's body fat is measured by bioelectrical impedance technology. Samsung conducted a clinical experiment and recruited 203 volunteers aged 65,438+08 ~ 68 at St. Mary's Hospital in Seoul. Samsung integrates the wristband and body of wearable devices into special sensors for data collection. After putting on the equipment, volunteers press the sensor on the front of their bodies with their fingers to form a current circulation with the human body, and then complete the body fat detection. The whole process is similar to measuring ECG with AppleWatch.

Samsung filed a patent on 20 15, which also indicates that Samsung may be developing a wristband with body fat measurement function, and will add a new function called "BodyComposition" to its smart wearable products, which allows users to measure body fat percentage through smart watches.

According to the patent document, the watchband is equipped with electrodes. When measurement is needed, the user only needs to put two fingers at the relevant positions for bioelectrical impedance analysis (BIA), that is, the ratio of fat to water can be calculated by using low-power current, and the resistance between adipose tissue and non-adipose tissue can be analyzed.

So far, there is no small device like smart watch on the market to measure the body fat of BIA. If Samsung's patent can be realized, it will be the same as the ECG function of AppleWatchSeries4, which is a major breakthrough for wearable devices in the field of health care.

What black technologies are available now?

Black technology that can be used now

1.3DVR virtual glasses

When it comes to VR glasses, everyone is no stranger. It is an artifact that can make you "immersive". The mobile phone turns into a 3D giant screen in seconds, so you don't have to go to the cinema to watch movies anymore! Whether watching movies or playing games, it's like really entering the scene. This kind of feeling is exciting to think about.

2. Lighter

Do you think this is a cigarette at first sight? Hey hey, you've been cheated! It is actually a lighter! The appearance is almost identical to that of ordinary cigarettes, and the size is not bad at all. Creative and cost-effective. Have you ever been surprised by such black technology?

3. Smart Bluetooth bracelet

With the improvement of living standards, everyone now attaches great importance to exercise and health. Friends circle and qq space are the number of walking steps and running laps every day, but the level of mobile phones in this respect is not high. On the other hand, bracelets are different. It can clearly help you monitor daily exercise, sleep and even air quality, and then lead a healthy life.

Plug-ins are indispensable things in daily life, but most of the words we use are ordinary and plain plug-ins. There are sockets on both sides of the mini Rubik's cube patch panel, as well as USB sockets, which is particularly convenient for charging mobile phones. What's even more amazing is that multiple patch panels can be plugged together, which subverts the traditional patch panels and is flexible and wonderful to use.

Definition of black technology

Black technology is a term appearing in All-Metal Frenzy, which was originally owned by listeners, but not independently developed by human beings. Beyond the existing scientific and technological knowledge of human beings, it extends to exotic products that cannot be understood by the existing world outlook of human beings. You can also refer to some self-made destruction techniques of technical houses, such as laser guns, electromagnetic guns and atomic bombs.

Black technology (primary) is far beyond the scope of human science and technology or knowledge, and its science and technology or products lack scientific basis and violate the principles of nature.

Black technology (native) can also refer to technology that seems impossible in real life. For example, in animation or novels, science and technology are invented to rationalize the plot. Most of these technologies have no theoretical basis, and some of them are pure nonsense, such as the Yang electric cannon in Seed, the GN particle in Gundam, the Magic Forbidden, and the railgun in Super Gun. In the game, black technology is given different explanations. Generally speaking, due to some special reasons (such as game vulnerabilities, cheating code, etc. ), players can break through the existing principle of fair play and win. It can also mean that in games (mostly card games and real-time strategy games), players break away from conventional ideas and adopt ingenious, unexpected and incredible gameplay and tactics, thus confusing opponents and winning the game.

Generally, technologies or products that cannot be realized or produced by human beings at present are collectively referred to as "black technology", and their standards do not conform to the common sense of the real world and the existing level of science and technology, such as technologies not disclosed by the government or mysterious organizations, such as SARSAIDS and its variants. Can be extended to some extraordinary things or real things.

Primitive black technology is equivalent to Zentraedi technology, and the word Primitive black technology comes from the meaning of Zentraedi technology. But it should be noted that their original works are different. The original work of Zentraedi technology is a fortress of time and space, and the original work of black technology is an all-metal frenzy.

Top ten black technology rankings

1, bionic eye

At present, argus's second-generation artificial retina system and the system being developed by Professor JohnPezari of Harvard Research Institute can transmit electronic signals to implanted electrodes through cameras. ArgusII can help patients who have lost part of their retinal function by implanting electrodes in their eyes.

2. Wearable kidneys

For people with kidney problems, basic survival requires a huge kidney washing machine to remove toxins from the blood and balance the fluids in the body. The wearable artificial kidney developed by MartinRoberts and DavidBNLee of UCLA can be more effective than the traditional kidney washer, because it can work 24 hours a day, just like a real kidney.

3. Portable pancreas

Artificial pancreas can detect people's blood sugar or regulate people's insulin demand. Kowalski said that the instrument will initially be a combination of two technologies: an insulin supplier and a glucose detector. This device allows patients to live a relatively normal life without worrying about the danger of high or low blood sugar.

4. Non-human taste

Tongue can be a very powerful tool or a very subjective tool. The equipment developed by Neikirk and his team can detect chemical components in liquids. Neikirk's tongue microsphere detector will change color when it touches some targets, such as some sugar. This can't replace a person who says "it's delicious", but he can ensure that the good taste of chemical components is reliably copied.

5. Mechanical arm

Amputees can now have the same prosthesis as real people: mind control. Professor ToddKuiken of Chicago Rehabilitation Institute has developed a bionic hand, which can be connected to the brain through the patient's primitive nerve.

6, smart knees

Human knees can't think, but RHEO, an artificial knee developed by HughHerr and AriWilkenfeld, artificial intelligence researchers at MIT, can have its own thoughts. He can make real and comfortable movements, learn how the user walks through the detector, and judge what kind of terrain he walks on. This system makes it easier for prosthetic users to walk.

7. Regenerate bone

1960, the researchers found that there is a kind of protein that can promote bone fibers to grow back to their own parts or damaged places. In 2005, researchers at UCLA used a specific protein to grow specific cells. This is called UCB- 1, and this protein has been used for bone regeneration to fix vertebrae and relieve patients' back pain.

8. Artificial cells

Artificial cells are made of aggregates and can imitate the behavior of white blood cells in blood vessels. These pseudocells can deliver drugs to where they are needed, and can repel some diseases, such as cancer, more simply and safely.

9. New reproductive organs

Erectile dysfunction can reduce men's interest, but AnthonyAtala of WakeForest University and his team have come up with a way to make new organs. In 2006, attalla successfully bred a new cavernous body, which will be congested during erection, so that the genitals of male rabbits that had been excised can grow back.

10, prosthesis in the brain

Replacing a part of the brain is more difficult than replacing limbs, but it may be realized in the future. TheodoreBerger, a professor at the University of Southern California, has made a computer chip that can replace the hippocampus and the part of the human brain that deals with short-term memory and spatial learning. Implantation of hippocampus, which is usually damaged by Alzheimer's disease or stroke, can restore patients' normal life.
