core tip: for many years, as one of the core sensing technologies of IOT, the popularization and application of RFID technology has been hampered by technology, price and cost, as well as user habits; However, in August this year, the control mode can be set as a good general mode of speed closed-loop and pressure closed-loop. At the first China Printing electronics industry joint exhibition and Summit Forum held at the same time with Shenzhen IOT exhibition, we learned the wonderful characteristics of printing electronics technology, and the "paper battery" realized through printing technology process is inextricably linked with RFID technology

[China Packaging News] for many years, as one of the core sensing technologies of IOT, the popularization and application of RFID technology has been hampered by technology, price cost, user habits and other aspects; However, at the first China Printing electronics industry joint exhibition and Summit Forum held at the same time with Shenzhen IOT in August this year, I learned the wonderful characteristics of printing electronics technology. The "paper battery" realized through printing technology process is inextricably linked with RFID technology

flexible tags and paper batteries

it is learned that RFID tags in the current market are divided into three categories: passive, semi-passive (also known as semi-active) and active, depending on whether the internal power supply of the tag is available. Among them, the active label must have a built-in power supply to supply the power required by the internal IC to generate external signals. The advantage of this kind of label is that it has a long reading distance and can accommodate a large memory capacity, but the drawback is that it needs to replace the battery regularly to prolong the working life. However, traditional battery forms, such as button batteries and lithium batteries, have been criticized in terms of volume and price. People have been looking forward to the launch of a lightweight and affordable battery product

on the "Changzhou enfosai Electronics" booth of this China printing and electronics industry joint exhibition, I saw the thin-film printing paper battery that has won the "Davos world economic forum Technology Pioneer Award". This kind of battery with thin film as carrier is coated with special ink made of conductive materials and carbon nano materials. The inventor of this product, Professor zhangxiachang, a Finnish Chinese scientist, is known as the "father of paper batteries" in the industry

Professor Zhang said that the thin-film printing paper battery has the characteristics of softness, lightness and thinness. Its power is equivalent to that of button battery, and it is a "future battery" that is more friendly to environmental protection. Paper battery can meet the current market demand for light and thin power supply, solve the shackles of energy supply in the development of printing electronics, and bring hope for light and efficient new energy storage. It will expand the application field of printing electronics again and realize the qualitative progress of the industry

it is reported that this "paper battery" is disposable, and the size, thickness and shape can be customized according to different user needs, as well as the position of the positive and negative poles of the battery can be adjusted. The company provides OEM services and can design the battery voltage above 3V. At present, "enfossa printing Electronics" is taking "paper battery" as the core, relying on its rich experience in material engineering, chemical formula, electrochemistry, electronic engineering, biology, etc., committed to the development and application of small power supplies with clean properties, and building an integrated platform with paper battery improvement and R & D, product application development, and application investment. At present, the four standard batteries provided by NFSA have an initial voltage of 1.5V and 3V, an initial capacity of 20~110mah, a thickness of 0.7mm, and a weight of only G; In addition, enfossa can also customize paper batteries of various special specifications according to customer requirements

it is reported that the company will integrate paper batteries into more terminal application products in the future, so that the terminal products can be processed and produced at one time in large-scale production lines and battery production. The terminal application products of paper battery will include all kinds of wearable devices, applications of ion penetration, such as cosmetics (eye mask battery), externally applied cream drugs; Flexible labels such as smart cards, temperature labels, smart sports such as marathon badges, golf club stickers, etc; Intelligent medical treatment, such as human skin (infant question detection), ECG detection and other fields

various applications of printed paper batteries

Professor Zhang concluded that the popularity of printing electronic technology has opened up a series of new products and application possibilities, including photovoltaic cells (sub tags) for mobile and fixed use, flexible batteries for mobile devices, thin film transistor (OTFT) backplanes, and smart devices for sensor disposable devices. Compared with traditional production methods, the advantages of printing electronic technology in improving production efficiency, improving product quality and reducing costs will make the printing electronic industry usher in explosive growth and development. The production and promotion of this technical product in China has filled the gap of "thin film battery" in China

recently, Changzhou enfosai and Changzhou printing and Electronics Industry Research Institute jointly developed an ultra-high data storage frequency RFID temperature monitoring tag for Japan relief printing Co., Ltd. Japan relief printing Co., Ltd. is a Japanese printing and packaging manufacturer and smart card manufacturer. The label is developed and made from free radicals based on the traditional RFID temperature sensing technology and the thin flexible paper battery technology originally created by Dr. Zhang xiachang. It can continuously monitor the temperature changes of food, drugs and other items that need constant temperature storage during the cold chain transportation, so as to ensure the safety and reliability of the cold chain transportation quality

established in 2010, Changzhou enfosai has been widely praised and praised by the whole society through the introduction of advanced "thin film battery" technology, and won the first prize in the "China Science and technology entrepreneurship competition" that year, with the support of the national innovation fund. In 2011, it was recognized by the State Council and awarded the honor of "key overseas Chinese entrepreneurship team". In 2012, the first general meeting of the national printing and electronics industry alliance elected Professor Zhang xiachang as the deputy secretary general and vice chairman. In 2013, the Changzhou printing and Electronics Industry Research Institute was established in cooperation with Changzhou municipal government. Professor Zhang xiachang was elected by colleagues in the industry as the president of the Institute. In 2014, the company developed a mature cold chain temperature sensing system (label and management platform) and established a subsidiary integrating production, operation and sales of related applications. The company continues to explore and innovate on the road of research, development and application of paper batteries and strives to make progress. In order to better develop and form a concentration of industrial advantages, the company is invited by Changzhou municipal government and will officially enter Changzhou printing and electronics industrial park at the end of 2016
