The application of stealth electronic products in modern packaging

Perhaps the hottest technology today is printed electronics. Its development speed is very alarming, and it does bring some benefits to users. When the invisible electronic product is mounted on a completely transparent carrier, it may need to be slightly bent. The world's largest printed electronics fair, the 2008 European Print Electronics Conference (sponsored by IDTechEx), was successfully held in Dresden, the famous German electronics center, from April 8th to 9th. The famous local Novaled The company released a record-breaking luminous ink at this exhibition and invited the audience to visit their bright and atmospheric new factory.

The speakers of this conference have expressed that we can now create a transparent feeling through printed transistors and other forms of electronic and electrical equipment. For example, solar cells coated on viewing glass can produce invisible currents.

Luminescent plastics were first discovered by the University of Cambridge in the United Kingdom, and dye-sensitized nanocrystalline thin-film solar cells were invented in Switzerland and are being produced on a large scale in the United Kingdom. Nanosolar, a well-known CIGS thin-film battery manufacturer in the US, also announced that it will use mass-production CIGS (copper indium gallium selenide) solar cell modules for the first time worldwide. This new battery module is characterized by very low production costs, and the cost of the area required for generating power per watt is only 0.99 US dollars. It is understood that the company has mass production plants in the United States on the outskirts of the city of San Jose and Germany, but the initial mass production will be carried out at a German factory. In addition, the use of roll-to-roll printing technology to produce transistors will further speed up the chip's entry into the market. German PolyIC has always been a leader in the printed electronics market. They have now developed photovoltaic cells with better performance than monocrystalline silicon solar cells.

Another development approach for invisible electronics is to use electronic systems printed inside the package—RFID labels replace the unsightly bar codes outside the package. In fact, some RFID tags are printed directly in the package—even in the sizing position of the package. Manroland, a world-renowned manufacturer of large-scale printing equipment, also emphasized the importance of eliminating bar codes and traditional RFID tags that are visible on the outside of packaging, and pointed out that the perfect combination of RFID and product packaging can not be separated from the active cooperation of printing plants. Thomas Walther, the company’s new product technology manager, said: “The latest market research shows that both marketing experts and consumers see packaging as the most effective media.”

At the beginning of printing invisible RFID antennas, we must have easy-to-use software and post-press processing equipment, while also taking into account the environmental issues of production. One of the most difficult things in this process is reading a lot of patent documents. However, as the use of RFID tags hidden in product packaging becomes more and more widespread, the development of antenna and chip implant (transistor printing) technology has also become faster and faster. This kind of printed electronic products can play a good role in combating fake and shoddy products, and can help related stores clean up the backlog of inventory as soon as possible. It can replace 10 trillion bar codes each year and significantly improve customer service. In other words, the potential of this new type of electronic technology is very large.

However, as Manroland pointed out, the printed electronics inside the packaging are not only related to the invisible circuit, but also related to advertising and entertainment. When you come across or otherwise start a package, you can not only see the image, but it is also possible to play the game. Someone once developed a paper that shows the moving image when you breathe into it. Almost everyone thinks that printed electronics is a booster for creative design? The speeches and presentations of the two artists at this exhibition have attracted a great deal of attention from the audience. From the ever-growing animated wallpapers and luminous images to prayer blankets that light up when heading towards Mecca, they all show us the magic of printed electronics. Another creative product is the carton alarm clock. When it wakes you up, you can either throw it or throw it in the trash to vent your feelings of depression. Surprisingly, this new type of printing device is very robust, and when you are finished, it can continue to be used.

For this new electronic world, intelligent substrates are a very important part. Ingrid Graz of the University of Cambridge's Center for Nanosciences described in detail in a speech entitled "Skin-like Electronics: Thin-Film Equipment Made Using Ultra-Low Temperature Technology" to describe in detail what she and her partners have achieved on this issue. She put forward three related goals: to create a shapeable, stretchable electronic product that can be combined with biological tissue. She pointed out the huge application potential of printed electronics in ergonomics and the human body (from fashion to electronic textiles to repair of skin and cells). If the electronic device has good tensile and rebound characteristics, it can also bring great convenience to our production and life.

In addition, how can light be used to make something transparent? Can we really produce a sudden disappearing car like that driven by James Bond (007)? Of course, in the eyes of physicists, Nothing is absolute. Because they have recently been able to surround a microwave around a certain frequency, making it transparent at this frequency. Thanks to the new onlooker structure, these materials can be used to produce new beam benders, modulators, bandpass filters, contact lenses, microwave couplers and radome etc. It is even claimed that with the press of a button, Can change some things, of course, these things must be painted with "magic" material.

Peter Harrop IDTechEx chairman said: "We will be held December 2 to 5 in San Francisco this exhibition companion ?? Printed Electronics USA General Assembly will have at least 1000 exhibitors come to the exhibition, the audience. At least six opportunities for visiting local universities and companies that have made breakthroughs in printed electronics are also available.If you have already missed the April Print Electronics Conference in April, I hope you can seize this valuable opportunity. To learn about the latest advances in printed electronics technology."
