Human understanding of the deep sea still lags far behind our imagination of outer space. Although more than 70% of the Earth’s surface is covered by oceans, only a small fraction of deep-sea regions has been systematically explored and documented. As deep-sea resource development, marine scientific research, and polar exploration continue to accelerate, a critical challenge has emerged: how to reliably identify, track, and manage equipment and samples in an extreme subsea environment characterized by high pressure, low temperature, severe corrosion, and the absence of GPS signals. This is where RFID technology is beginning to play an increasingly important role in deep-sea operations. 1. The Information Blind Spots of Deep-Sea Operations In traditional deep-sea missions, whether involving ROVs (Remotely Operated Vehicles), AUVs (Autonomous Underwater Vehicles), or deep-sea landers and sampling tools, information management has largely relied on manual labeling, video review, and mission logs. These approaches suffer from several inherent limitations. First, real-time verification is difficult; errors in sample recovery are often discovered only after the equipment returns to the surface. Second, data linkage is weak—equipment IDs, samples, timestamps, and depth information are often stored separately, making it hard to establish a complete traceability chain. Third, during long-term or multi-expedition projects, equipment mix-ups and sample misidentification remain common risks. As deep-sea exploration moves toward larger-scale and more systematic operations, traditional manual methods are no longer sufficient. 2. Why RFID Is Well Suited for Deep-Sea Environments RFID was not originally designed for deep-sea applications, yet several of its inherent characteristics make it particularly suitable for subsea use. First, RFID does not rely on line-of-sight. Unlike QR codes or visual markers, RFID uses radio-frequency communication, enabling stable identification even in turbid water and low-light conditions. Second, RFID components can be robustly encapsulated. In deep-sea scenarios, antennas such as RFID ceramic antennas are especially valuable due to their excellent resistance to high pressure, saltwater corrosion, and long-term environmental stress. Third, RFID provides unique identification. Each tag carries a globally unique ID, effectively creating a “digital identity” for every piece of equipment or sample—an essential foundation for deep-sea data systems. For compact subsea instruments and sampling containers, small UHF RFID antennas can be embedded directly into housings without affecting mechanical integrity, enabling identification while preserving streamlined structural design. In underwater applications, RFID is typically deployed for short-range identification, often operating in coordination with underwater communication systems rather than attempting long-distance wireless transmission. 3. Intelligent Identification and Management of...

Behind the frequently mentioned phrase “the brain-inspired era” lies a profound paradigm shift. Artificial intelligence is no longer driven only by bigger models and more computing power, but is beginning to learn from the human brain itself: perception, association, memory, decision-making, and evolution. Models are becoming more like a “digital brain.” Yet a fundamental question emerges: how can such a brain truly understand the real world? Without perceptual gateways, even the most powerful neural network is merely an “island of intelligence” trapped inside data. In this context, RFID is quietly becoming the first critical bridge connecting the physical world with brain-inspired intelligence. Traditional AI mainly learns from text, images, and speech on the internet — a “described world.” But true brain-inspired intelligence needs a “perceived world.” Just as a baby does not learn by reading books, but by touching, grasping, and observing, machines must build cognition through direct interaction with reality. UHF RFID tags — including specialized forms such as UHF RFID sport tags — act as the “sensory neurons” of this system, giving every object a unique, readable digital identity. When billions of items become perceptible, the world itself turns into a living perceptual map for neural networks. Technically, RFID is far more than an advanced barcode. It is a neural encoder for the physical world. RFID ceramic antennas enable stable and reliable sensing in harsh environments such as metal surfaces, high temperatures, and industrial workshops, while long-range and directional reader architectures provide spatial perception similar to human vision. A long range RFID reader module combined with a directional RFID reader gives the system “far-sight” and “focus,” allowing machines to understand where objects are, how they move, and how they interact in space — exactly like a visual cortex for the industrial world. In brain-inspired systems, perception is never isolated. It is tightly coupled with memory, reasoning, and prediction. RFID’s unique strength lies in its built-in time dimension and causal traceability. From raw material to finished product, every lifecycle event is captured by UHF RFID, forming an “experience memory” for neural networks. When an anomaly occurs, the system recalls similar sensory histories and predicts failure paths, making decisions closer to human intuition. In manufacturing, this bridge is already transforming factories. Traditional digital plants rely on dashboards; brain-inspired factories rely on perception. RFID-enabled machines, tools, and materials become part of a living sensory network. With ceramic-antenna-based tags surviving harsh production lines and long-range readers covering wide shop-floor areas, neural networks learn process laws, quality causality, and hidden risk patterns. The factory evolves from automation to cognition. In logistics and smart cities, the same architecture scales into a “sensory nerv...

In life sciences, medical diagnostics, and biopharmaceutical research, laboratories are no longer defined solely by test tubes and microscopes. As testing volumes grow, sample types diversify, and regulatory requirements become increasingly stringent, traditional laboratory management models—largely dependent on manual records and barcode-based identification—are revealing clear limitations. Issues such as low efficiency, high error rates, and insufficient traceability have become difficult to ignore. Against this backdrop, Radio Frequency Identification (RFID) technology is emerging as a foundational enabler of laboratory automation and digital transformation, particularly in the end-to-end management of biological samples. Challenges in Biological Sample Management Biological samples are highly sensitive and often irreplaceable. Whether dealing with blood, tissue sections, DNA samples, or cell cultures, any mix-up, contamination, or loss can compromise experimental results, derail research projects, or even lead to regulatory violations. In hospital laboratories, biobanks, and third-party testing facilities, thousands of samples may circulate daily, passing through tightly coupled stages such as collection, aliquoting, testing, storage, and transportation. While barcode systems have improved basic identification, they still rely heavily on manual scanning and visual confirmation. Labels can easily degrade under chemical exposure or ultra-low temperatures. In contrast, UHF RFID stickers designed for laboratory use can be securely attached to sample tubes and cryogenic containers, maintaining stable performance throughout high-throughput workflows and harsh storage conditions. RFID as the Foundation of Laboratory Automation Compared with barcodes, RFID offers significant advantages, including contactless operation, bulk reading capabilities, and stronger adaptability to harsh environments. By embedding RFID tags into sample tubes, cryoboxes, or transport trays, laboratories can identify and track samples without opening containers or performing individual scans. Within an automated laboratory ecosystem, RFID is more than a simple identification tool—it acts as a critical link connecting samples, equipment, and information systems. Industrial-grade RFID readers deployed at workstations, storage entrances, and transfer points ensure stable and accurate data capture even in electromagnetically complex laboratory environments. When integrated with Laboratory Information Management Systems (LIMS), automated aliquoting instruments, and cold-chain storage systems, RFID enables a sample-centric data network. Samples are automatically logged, verified, and tracked as they move through each process, significantly reducing reliance on manual intervention. End-to-End RFID Applications in Sample Workflows At the sample collection stage, RFID tags can be assigned and bound to sample data at the point of origin, minimizing the risks associated with delayed or m...

The progress of autonomous driving is often described as a competition in algorithms, computing power, and sensors. In reality, it is increasingly becoming a systems challenge—one that depends on how effectively vehicles and roads can work together. Relying solely on cameras, millimeter-wave radar, or LiDAR still leaves autonomous vehicles vulnerable to unstable recognition, environmental interference, and high system redundancy costs. Against this backdrop, RFID technology is being re-evaluated, gradually moving from logistics and manufacturing into intelligent road infrastructure and RFID vehicle management systems. From “Seeing” the Road to “Understanding” It Most autonomous vehicles today interpret road conditions through visual and radar-based perception. Lane markings, traffic signs, signals, and obstacles are detected passively, based on what sensors can observe at a given moment. Under ideal conditions, this works well. However, rain, snow, fog, glare, worn lane markings, or temporary construction zones quickly expose the limits of this approach. The road itself remains silent, offering no direct confirmation of what a vehicle believes it sees. RFID markers change this relationship. By embedding RFID tags into key road elements—lanes, intersections, speed-control zones, construction areas, and roadside infrastructure—the road gains a digital identity that can be read directly by vehicles. With properly designed UHF RFID antennas installed on vehicles or embedded near the roadway, information can be captured reliably without dependence on visibility or lighting conditions. How RFID Is Deployed in Intelligent Road Systems In road environments, RFID typically takes the form of passive UHF tags or ruggedized, weather-resistant markers installed beneath the road surface, along curbs, within guardrails, or inside traffic facilities. Autonomous vehicles equipped with onboard RFID readers can automatically detect these markers as they pass, without any active interaction. To support stable reading at driving speeds, vehicles often integrate a long-range RFID reader module, allowing tags to be identified early enough for decision-making. Each tag can store standardized information such as road classification, speed limits, lane attributes, intersection identifiers, or warnings related to temporary conditions. When integrated with high-definition maps and vehicle control systems, RFID enables vehicles to anticipate road conditions rather than react to them. Enhancing Positioning Accuracy Where GPS Falls Short High-precision positioning remains one of the most difficult challenges in autonomous driving. Even when combining GNSS, inertial measurement units, and visual SLAM, location drift can occur in tunnels, dense urban areas, or locations with poor satellite coverage. RFID markers provide fixed physical reference points. Each time a vehicle reads a tag, it can recalibrate its position with high confidence. This approach has proven particularly val...

Against the backdrop of carbon neutrality goals and the growing emphasis on the circular economy, waste recycling is no longer a simple process of collection, transportation, and dismantling. Instead, it has evolved into a systematic project encompassing product design, usage management, recycling traceability, and resource regeneration. In practice, low recycling efficiency, unclear sources, opaque material flows, and weak accountability continue to constrain the large-scale development of green recycling systems. Enabling waste items to be identified, understood, and tracked throughout the recycling process has become a critical challenge. RFID technology is emerging as a powerful solution to this problem. From Anonymous Waste to Digital Identity In traditional recycling systems, most waste items lose their “identity” once they enter the recycling stage. Recycling enterprises often rely on visual inspection, experience, or manual sorting, resulting in low efficiency and high error rates. By embedding RFID tags into products or packaging, each item is assigned a unique digital identity from the very beginning. For large-scale consumer goods and packaging waste, UHF RFID stickers provide a cost-effective and scalable solution, allowing product information such as model, material composition, production batch, service life, and maintenance history to be stored and retrieved efficiently. When the product reaches the end of its usable life and enters the recycling stream, RFID readers can instantly identify and extract this data. Waste items are no longer silent resources—they become data carriers capable of “communicating” their remaining value. Building a Fully Traceable Lifecycle Chain The core of green recycling lies in full lifecycle management. The value of RFID extends far beyond the recycling stage and runs through every phase of a product’s life, from manufacturing and distribution to use and disposal. During production, RFID tags record material sources and environmental attributes, laying the foundation for future disassembly and reuse. In industries involving metal components, electronic assemblies, or high-temperature processes, RFID ceramic antennas ensure stable tag performance under harsh conditions, enabling reliable identification even after prolonged use or exposure. During circulation and usage, RFID supports asset management and reduces losses and excessive consumption. At the end-of-life stage, systems can automatically determine whether an item is suitable for remanufacturing, component recovery, or material-level recycling based on lifecycle data. This closed-loop data structure transforms recycling from an endpoint into the starting point of a new resource cycle, enabling recycling systems to become measurable, auditable, and continuously optimizable. Improving Efficiency and Reducing Operational Costs The recycling industry has long been characterized by high labor dependence and extensive management practices. RFID’s abili...

Over the past few years, the concept of the “metaverse” has transformed from speculative hype into a more grounded exploration. As virtual environments grow increasingly realistic, it has become evident that without stable, accurate and low-cost connections to the physical world, immersive digital life cannot fully materialize. In this context, RFID technology has regained strategic importance. Traditionally used in logistics, retail and transportation, RFID now plays a new role in virtual-physical fusion: enabling real-world people, items and assets to form trackable, computable and verifiable “digital twins” in the metaverse. To support this shift, hardware capabilities have also evolved. Modern RFID infrastructures now incorporate advanced components such as UHF RFID modules for high-speed identification, RFID ceramic antennas for compact and stable tag performance, and directional RFID readers capable of pinpointing tag orientation and movement—technologies that significantly enhance the precision required for metaverse applications. 1. The Core Challenge of Virtual–Physical Convergence: Missing Real-World Data Virtual worlds depend on rendering and simulation, but the real world’s behavior, object flow and identity states are just as critical. To achieve meaningful interaction between virtual and physical realms, several fundamental questions must be answered: — Who owns this physical object? — Where is it now? — Has it been used, borrowed or damaged? — Does it correspond to a virtual asset? — Can real-world changes be synchronized instantly? These questions seem simple but are difficult to automate at scale. RFID, equipped with high-performance UHF modules and flexible antenna designs, enables massive, real-time, low-maintenance data capture. Compared with QR codes, RFID is more automated; compared with Bluetooth, more economical; and compared with vision systems, more stable and not affected by lighting. Because of this, RFID is increasingly regarded as the foundational data bridge connecting physical and virtual layers. 2. RFID-Based Object Mapping: Giving Virtual Assets a Real-World Foundation Virtual assets in the metaverse are treated as collectible, tradable and displayable digital goods. Yet their connection to real-world items is often vague. RFID solves this by giving every physical object a unique, non-replicable electronic identity, which can be synchronized with cloud platforms or virtual environments. For example, in sneaker collecting, limited-edition toys or fine art, RFID tags—often using RFID ceramic antenna designs for compactness and durability—can store ownership, authenticity, usage patterns and transfer history. These data points become the backbone of the object’s digital twin. — Buy a physical collectible → automatically receive the same asset in the metaverse. — Resell the object → virtual ownership updates instantly. — Physical wear or repair → reflected in the digital version. This real-world anchoring makes virtu...
