New foreign RFID patent: detect peoples activities without wearing labels 
 In July, researchers at the University of Glasgow recently made a breakthrough in developing a new RFID tracking system that can track the behavior of the elderly or high-risk groups at home without wearing any RFID labels. This innovative technology has been named "Transparent RFID Label Wall" (TRT wall) and has been patented for the system. 
 The system does not directly identify when RFID tags are read, but infers the existence and activities of people by analyzing when and how tag readings are interrupted. When someone moves between walls, their bodies will slightly interfere with the transmission of RFID signals. The degree and method of interference are enough to be captured and analyzed by the system to identify movements such as walking speed, sitting posture, standing posture and even falling. 
 Several European countries have approved rfid technology to use the 915-921MHz band, and the global compatibility of RFID has been significantly improved. 
 In the past, UHF RFID systems faced global challenges, because RFIDs in different countries used different frequency bands, and products designed for one bandwidth may not be approved for operation in another country. In some cases, this has inhibited the development of global RFID technologies and solutions. 
 In recent years, Europe has made remarkable progress in the field of ultra-high frequency RFID technology. Recently, 11 European countries have approved the use of the 915-921 MHz band for RFID. The newly acceded countries are Austria, the Czech Republic, Croatia, Latvia, Malta, Montenegro, Poland, Romania, Sweden, Serbia and Turkey, bringing the total number of European participating countries to 35. 
 University of California launches a new passive RFID sensor 
 On November 5, the research team of the Department of Electrical and Computer Engineering at the University of California, San Diego presented their research at the 22nd ACM Embedded Network Sensor System Conference (SenSys 2024) held in Hangzhou, China: the use of RFID tags to achieve battery-free sensing. This breakthrough research not only broadens the application scope of sensors, but also opens up a new path for the future of data collection. Traditional passive sensing methods mostly rely on analog-to-digital converters, which can measure stimuli and convert them into computer-readable digital values, they consume a lot of power and require additional battery support. Bhat and Bharadia are trying to explore a way to directly use chips to sense stimuli without converters. 
 They found that analog induction interfaces are the key to solving this problem. Unlike digital interfaces, analog interfaces can directly convert the voltage/current changes generated by sensors into parameters of wireless signals, thus realizing the wireless transmission of data. As a commercial, low-cost and easily accessible sensor device, RFID label is ideal for achieving this goal. Bhat and Bharadias sensors are not only cheap, but also have the ability to detect and report stimuli in real time. This means that this battery-free RFID sensor can provide more accurate and timely data, whether in the fields of agricultural management, sports performance indicators or occupation detection. 
 Chipless pure paper rfid label is about to be piloted, and the cost will be halved and the profit margin will be increased by 30%. 
 PulpaTronics has proposed an innovative solution - completely chip-free and metal-free paper smart labels. This technology is not only an innovation of traditional RFID technology, but also an in-depth practice of the concept of sustainable development. Compared with traditional metal RFID labels, PulpaTronics paper-based smart label reduces carbon dioxide emissions by 70% during manufacturing and half the cost. The key to this technological breakthrough is to use laser technology to induct the conductive circuit directly from the substrate to convert the carbon composition in the paper into a conductive carbon-based material closer to graphite or graphene. In this way, PulpaTronics simplifies the whole manufacturing process, and the final product is only one piece of paper, which is environmentally friendly and economical. 
 In terms of specific marketing plans, PulpaTronics has formulated a detailed 18-month development plan. Careful arrangements have been made from the finalization of product specifications to internal production, piloting with retail and packaging partners, designing large production lines and cooperation with suppliers. So said that PulpaTronics will first bring its hybrid products to the market, which can be seamlessly integrated into the existing infrastructure and run in the same way, while providing higher cost-effectiveness and sustainability. 
 Qualcomm claims that it is integrating RFID functions into mobile phone chips. 
 In December, Qualcomm announced its plan to integrate UHF RFID functions into its mobile device chipset. In fact, Qualcomm has been working closely with partners such as Impinj, the manufacturer of UHF RFID chip, and retailer Decathlon to promote the integrated application of RFID technology on mobile phones and mobile devices. All parties are working together to overcome technical obstacles and promote the popularization and development of RFID technology. Qualcomm plans to focus on launching enterprise mobile devices equipped with RFID technology in several quarters, and consumer devices are expected to follow suit.
