Introduction
Ⅰ. Foreword
Human skin, showing notable features, is a physical barrier for us to interact with the surrounding environment, which enables us to perceive different shapes and textures, temperature changes, and different levels of contact pressure.It is an integrated, scalable sensor network that delivers tactile and thermal signals to the brain, enabling us to operate safely and efficiently in the surroundings. Inspired by these characteristics of the human skin, researchers are working to create a flexible, scalable, highly sensitive electronic device. Therefore, the development of electronic skin has become a research hotspot, especially in the fields of intelligent robot and e-health.
Basic functions of electronic skin:
  1. 1. From obtaining physical stimuli to distributed sensor arrays;
  2. 2. Preprocessing sensor signal;
  3. 3. Wireless transmission of signals to higher-level systems (e.g. smartphones)
While some of the current wearables also offer these features, but can not reach the wafer-thinness, feather-lightness, high strain sensitivity as ultra-thin electronic skins. More importantly, the electronic skin is equipped with highly sensitive conductive nanomaterials, which can accurately induce a slight tremor of electrical change of a muscle group. At the same time, electronic skin is scalable (for example, it supports joint motion), and can even form integrated chemical sensors and biosensors. The adhesion of electronic skin is better, the preparation process is simpler and the cost is lower, which makes us would like to say the future market will belong to electronic skin. In this article, We'll have a discussion about electronic skin in three aspects: the development, the architecture system in e-health field and the applications of it, and in the end the future and prospect of e-skin have also been discussed.

A micro-electronic health monitor so thin, light and portable that it can attach right to the surface of skin and go wherever a person goes. This innovation has the potential to revolutionize the field of healthcare technology.
Ⅱ. The development of electronic skin technology could be divided into two stages:
  1. 1)From 1970s to 1990s, the concept of e-skin appeared for the first time and got a preliminary development.
  2. 2)Since 2000s, more researchers have been involved and have made a significant progress in recent years.
In 1974, Clippinger demonstrated the feedback of a discrete sensor for a prosthetic hand. In 1985, General Electric first built a robotic arm sensitive skin which enabled to interact with the environment, placed on a flexible, curved sheet using discrete infrared sensors. In the 1990s, more and more teams began to create large-area, ultra-thin, multi-sensor flexible sheets. Jiang et al. first proposed a bent sensor sheet which obtained by etching thin silicon wafers and then integrating them on flexible polyimide film. In 2000, the organic transistor electronic nose was developed. Later, more achievements were made, such as scalable inverters, flexible active matrix technology, high resolution optical sensors, microstructured pressure sensors and so on. In 2003, the research team at the University of Tokyo in Japan made thin films by using low molecular organic compounds and realized the pressure of electronic skin through the pressure sensors on its surface. In 2010, the University of California, Berkeley, developed a technology to attach nanowire transistors to a sticky substrate, the resulting e-skin therefor could apperceive less than 50 grams of fine pressure and has been subjected to bending 2000 times. A woman scientist of Stanford University Bao Zhenan and her team have developed a highly sensitive flexible plastic film material that mimics human skin and senses subtle pressure. At the same time, the team developed the world's newest stretch solar cells, allowing electronic skin to self-generate electricity. In 2011, a researcher named John A.Rogers introduced an electronic patch for monitoring patient vital signs which described as "electronic skin." This device embedded the sensors in a film and placed the film on a flexible polyester substrate, like a kind of tattoo on the body. physiological indexes of human health In 2014, electronic skin, developed by a researcher from the Chinese Academy of Sciences, was pasted on the human skin by static electricity, enabling real-time monitoring of physiological indexes of human health such as pulse, heartbeat, body temperature, muscle group vibration and so on, to promptly make a respond with feedback on changes of human health data.

Detail
Ⅲ. Electronic skin system architecture
Compared with the current intelligent wearable devices, electronic skin has the characteristics of high sensitivity, ultra-thin, bendability and comfort in guardianship and monitoring the important physiological information of human body. E-skin system is a new type of flexible and extensible sensing system. By making sensors and circuits built on flexible substrates, e-skin systems can obtain unique ductility and more sensible to the various physical, chemical and biological signals. In the field of health care, the emergence of electronic skin will change the imprecise measurement of wearable devices, reduce the number of heavy monitoring equipment in the ward, and enable medical staff obtain the patient's physiological parameters in real time.

Analysis of the working principle of UP6103 chip.

MSI produces a large number of municipal motherboards that use UP6103 chips to control motherboard memory to power electricity and bridges. Because of the high usage rate, the chip is damaged more. The UP6103 chip works as shown in figure 1.
UP6103 works as follows.
1. 12V voltage through diode D4, current limiting resistance 2.2Ω, to UP6103 5-pin power supply, UP6103 through the internal circuit to supply 1-pin power.
2. 5VDIMIN supplies the D pole of the MOS tube Q31.
3. After the tap switch is triggered, the bridge sends out a SLP_S5 high-level signal that is sent to the B pole of the transistor Q17 via the 10kΩresistor R53, making the Q17 on and the C pole pulled to a low level. The G of MOS Q18 is extremely low and Q18 is cut off. After the resistance R29 pull up the 0.9V SIO_DDR_MREF signal to the UP6103-7 feet, turn on the chip to work.
4. UP6103 controls Q31 from a 2-pin output signal, 5VDIMM_IN charges inductors and capacitors through Q31, and outputs VCC_DDR voltage to power memory.
5. After the Q31 leads, the inductor and capacitor charge slowly, and the VCC_DDR voltage will rise slowly. The VCC_DDR is sent to the 6-pin of the UP6103 chip via resistance R2, and then sampled from the resistor R4 and R37, and is compared internally with the 7-pin 0.9V voltage.
 6. When the 6-pin voltage of the UP6103 is higher than 0.9V, the UP6103 controls the 2-pin output signal to turn off Q31 and turn Q35 on from the 4-pin output signal.
7. Q35 leads to the formation of a closed loop, inductance, capacitor discharge output VCC_DDR voltage for memory power supply. The VCC_DDR voltage decreases slowly during discharge and returns to the 6-pin of the UP6103 chip after sampling the anode.
8. When the 6-pin voltage of the UP6103 is less than 0.9V, the chip closes the lower Q37 and reopens the upper Q31 to charge.
9. Q31. Under UP6103 control Q37 cycle operation, after capacitor filter output smooth VCC_DDR voltage to power the memory.

Eight guidelines for handling artificial intelligence (AI)

BVDW has released eight guidelines for handling artificial intelligence (AI). These guidelines address issues such as digital ethics, labor market challenges or business communication with politics and society.

In the context of the growing importance of artificial intelligence and its impact on society, the economy, and politics, the Federal Digital Economy Association (BVDW) has agreed on eight guidelines for dealing with artificial intelligence. The guide was developed by the “Artificial Intelligence Expert Group”, which consists of representatives from various associations.

Artificial intelligence is an economic competitive factor. However, in the foreground, it is no longer just the technical possibilities of AI. We are eager to address development issues in a more comprehensive manner. Marco Zingler, vice president of BVDW, explained that the focus is not just on what artificial intelligence can do, but on what it should not do. Therefore, the digital industry will strive to communicate at a line of sight that involves society, business, and politics.

In order to maintain global competitiveness, the European digital economy must act in a closed manner,” BVDW Vice President requested.

8 guide details:
  1. Artificial intelligence is an economic competitive factor as a key technology, and the digital industry will involve artificial intelligence to develop new business models. To this end, companies in the digital economy must determine the specific application areas of AI.


2. KI helps solve social problems - the digital economy will accompany and mitigate this necessary discourse. To this end, economic, political and social equivals must be included.

3. Europe's digital economy needs to be cohesive to avoid falling behind - the implementation of artificial intelligence requires a European way of thinking. In order for the EU to act fully, Germany must become a strong member of the European Union.

4. Citizens' autonomy and freedom must be secured by building trust, and the digital economy believes that it has an obligation to adjust its data-driven models. Therefore, it must be clear which data is used by the intended AI.

5. Artificial intelligence has the potential to undermine the economy - clarifying basic ethical issues is a key prerequisite for its breakthrough. This requires clear guidelines for the entire society.

6. Breakthroughs in artificial intelligence will change the job market - the digital economy will use artificial intelligence to create new jobs in the labor market. This requires greater flexibility in the labor market.

7. The development of qualified AI experts in Germany and Europe is a top priority - the digital economy matches the conditions and their contribution. In addition, existing training and continuing education opportunities must be adjusted to make them more flexible.

8. Data is the driving force behind artificial intelligence - The digital economy is committed to providing an appropriate regulatory framework to implement artificial intelligence on a broad basis. The data tank needs to be opened to make the data available to help the AI break through.

KI - 2019 theme

Most importantly, however, clarifying basic ethical issues in accordance with the Association's artificial intelligence guidelines is a necessary prerequisite for technological breakthroughs. Zingler explained, “This requires trust, which can only be achieved through transparency and continuing education. In particular, the labor market is expected to change dramatically – as an industry, we have a responsibility to create new job files to compensate for unemployment and Establish appropriate artificial intelligence skills. After all, KI offers great potential for efficiency in Germany, for example in the industrial manufacturing process, if the appropriate regulatory framework allows it. With our guidelines, we give the digital economy an important direction.

AI is the same as the digital economy this year, no other development - a BVDW member survey, this year's trend shows: KI to 2019 with the most influential theme of the digital industry is. “In many discussions, AI is confused with pure automation,” Zingler said. But this does not meet the potential of this development. The actual ability to imitate through software-like human decision-making is a shift. “This is why AI is a fairly basic innovation that will affect some business models and social life.

Analysis of the use of electric oven

Nowadays, DIY baking is becoming more and more popular. The convenience of material purchase and the versatility of baking equipment have made many housewives immersed in the baking culture. And if you want to live a life that you can eat your own daily baked food, how can you reduce the electric oven? It is versatile and highly sought after.

The electric oven is an electric appliance that uses the radiant heat from the electric heating element to bake food, so pay attention to its radiation protection before purchasing. In addition, the taste of the baked food depends on the accuracy of the temperature, so it is necessary to choose an electric oven that can precisely control the temperature. Moreover, the temperature of the electric oven varies greatly, and the material used for baking needs to have good heat dissipation performance. In summary, before using the electric oven, you should buy a well-known electric oven, let yourself be reassured, use it with peace of mind, and eat with confidence.

The following describes the use of the electric oven

1.Dry the food
It is well known that some dry foods are stored at home for a long time, and it is easy to become wet and affect the taste. At this time, you can use the electric oven to make these small snacks dry again and become crispy and delicious.

2. Making pastries
I believe many people originally bought electric ovens to make cakes. There are many kinds of cakes, and the taste is excellent. It is a delicious food that you like. And if you want to make a beautiful pastry like the outside, you still have to study hard. After all, the electric oven is just a tool. If you want to eat food, you have to see if you are a person who loves to learn.

3. Processing snacks
Nowadays, there are many kinds of snacks. There are also various teaching videos on the Internet to teach people how to make healthy and delicious snacks. If you want to make your own snacks change more flavors, you can try it with an electric oven.

4. Yeast dough
With the advancement of technology, the function of electric ovens is now more and more. For example, even the yeast dough can be fermented in the fermentation file that comes with the electric oven, and the taste is not naturally lost. It is worth noting that the electric oven is fermented much faster than natural fermentation. If you are impatient with food, you should use an electric oven!

5. Grilled Chinese food
Chinese cuisine is delicious and the eight major cuisines are famous all over the world. The same material, different practices, a completely different taste, the electric oven can do it. Usually you use ordinary pan roast, grilled shrimp, grilled eggplant and electric oven to make a lot of taste, if you don't believe, you can try it, I believe you will fall in love with the oven to cook!

Through the above introduction, I believe that you have a certain understanding of the use of the electric oven, I hope to help you.
