When it comes to transformers, what comes to mind? Is it the gray iron box humming in the corner of the community, or the small and delicate coil components in electronic devices? In fact, transformers have long penetrated every aspect of our lives and industrial production.From household electricity to intelligent manufacturing, they are indispensable for their "silent dedication".  And different types of transformers, with their unique performances, shine in different scenarios.

Toroidal Transformers: Synonymous with Efficiency and Stability

The first time you see a toroidal transformer, it's easy to be attracted by its simple shape - a closed toroidal iron core with coils evenly wound around it.There are no redundant structures, but it contains strong performance. This structure gives it excellent magnetic circuit closure, low magnetic leakage, and high efficiency. In fields such as audio equipment and medical devices that have high requirements for power supply stability, toroidal transformers are almost the "standard configuration". It can effectively reduce electromagnetic interference, making the equipment run more stably and the sound quality purer. This is why many high-end audio enthusiasts favor it.

High-Frequency Electronic Transformers: Leaders in Miniaturization and High Speed

With the development of electronic devices towards miniaturization and lightweight, high-frequency electronic transformers have emerged as the times require. Its operating frequency is much higher than that of traditional transformers, which gives it a huge advantage in volume and weight.  In devices such as mobile phone chargers, laptop power adapters, and new energy vehicle charging piles, high-frequency electronic transformers play a key role. It can quickly realize voltage conversion, improve energy utilization efficiency, and enable these portable devices to exert powerful functions in limited space.  Nowadays, with the development of 5G communication, the Internet of Things and other technologies, the demand for high-frequency electronic transformers is still growing, and their performance is also continuously upgrading.

Low-Frequency Transformers: The "Steady Pillars" in the Industrial Field

Different from high-frequency electronic transformers, low-frequency transformers are more like the "steady pillars" in the industrial field.  It operates at a low frequency, has a relatively solid structure, and can run stably in environments with large currents and high voltages.  In scenarios such as power transmission, machine tools, and large industrial machinery, low-frequency transformers are responsible for converting high-voltage electricity into low-voltage electricity suitable for equipment use, or performing voltage isolation to ensure the safety of equipment and personnel.  Its reliability is an important guarantee for the continuous and stable operation of industrial production.  Although it seems "low-key", it is indispensable.

Encapsulated transformer: "Tough Warriors" in Harsh Environments

In some special environments, such as humid, dusty, vibrating or corrosive gas environments, ordinary transformers are prone to failure. Encapsulated transformer are like "tough warriors" born to deal with these harsh environments.  It completely wraps the coil and iron core with special potting materials (such as epoxy resin) to form a sealed whole. This enables it to have excellent waterproof, moisture-proof, dust-proof, shock-proof and anti-corrosion properties, playing an important role in fields such as outdoor lighting, automotive electronics, and industrial control.        Even in harsh environments, it can maintain a stable working state.

Professor Lai Yuekun’s team from Fuzhou University has conducted innovative research addressing the urgent demand for strong adhesive hydrogels in fields such as wearable sensors, soft robotics, tissue engineering, and wound dressings. Currently, interface adhesive materials face two major technical challenges: firstly, difficulty in achieving rapid and reversible switching between adhesive and non-adhesive states; secondly, poor adhesion performance in multi-liquid environments. Recently, the team conducted in-depth studies using the CIQTEK scanning electron microscope.

The PANC/T hydrogel was synthesized from acrylamide (AAm), N-isopropylacrylamide (NIPAM), a micellar solution composed of sodium dodecyl sulfate/methyl octadecyl methacrylate/sodium chloride (SDS/OMA/NaCl), and phosphotungstic acid (PTA). Dynamic interactions between PNIPAM chains and SDS enabled on-demand adhesion and separation. Further soaking in Fe³⁺ solution produced the PANC/T-Fe hydrogel, which achieves strong adhesion in various wet environments. This resulted in the development of an intelligent interface adhesive hydrogel with rapid responsiveness, capable of controlled adhesion and separation under different humidity conditions.

The research was published in Advanced Functional Materials under the title "Temperature-Mediated Controllable Adhesive Hydrogels with Remarkable Wet Adhesion Properties Based on Dynamic Interchain Interactions."

Synthesis and Structural Characteristics of Controllable Adhesive Hydrogel

PANC/T-Fe hydrogel is synthesized by copolymerization of hydrophilic AAm, amphiphilic NIPAM, and hydrophobic OMA. PTA acts as a crosslinker, forming hydrogen bonds with amino groups on polymer chains to establish a stable network. The team discovered that interactions between NIPAM and SDS are critical to the hydrogel’s temperature-sensitive adhesion. At lower temperatures, SDS crystallizes and adheres to PNIPAM chains, hindering adhesive functional groups from interacting with substrates and reducing adhesion. As temperature rises, SDS crystals melt, improving contact between adhesive groups and substrates and significantly increasing adhesion. PTA enhances adhesion at higher temperatures by physically interacting with polymer amino groups; this interaction weakens upon heating, softening the hydrogel and generating more adhesive sites. The dynamic regulation between polymer chains enables reversible, on-demand adhesion.

Figure 1. Hydrogel synthesis and mechanism of reversible wet adhesion.

Temperature Regulation Mechanism of Adhesion Performance

Through comparative experiments, the team confirmed that the synergistic effect of NIPAM and the micellar solution is key to the hydrogel’s temperature-sensitive adhesion. Differential Scanning Calorimetry (DSC) results indicate the temperature response is unrelated to NIPAM’s Lower Critical Solution Temperature (LCST), but influenced by NIPAM-SDS interactions, which alter SDS crystallization temperature. In situ FT-IR testing revealed that increasing temperature weakens interchain hydrogen bonds, releasing more adhesive groups and enhancing adhesion. Rheological analysis further verified temperature-dependent changes in molecular interactions, causing the hydrogel to shift from rigid to flexible.

Figure 2. Mechanism study of temperature-sensitive adhesion.

On-Demand Adhesion and Strong Wet Adhesion Performance

PANC/T-Fe hydrogel exhibits on-demand adhesion without external energy input, achievable by simple ice application. At room temperature (25°C), the hydrogel is soft and highly adhesive, making it difficult to peel from glass without leaving residue. Ice treatment enhances internal cohesion and elasticity, facilitating benign detachment and reducing adhesion strength. Adhesion remained stable over multiple cycles between 5°C and 25°C, demonstrating good reversibility. The hydrogel’s controllable adhesion under various environments holds significant potential in tissue healing, material repair, and wet-environment actuators.

Figure 3. Performance testing of reversible adhesion.

Wet Adhesion Performance in Various Liquid Environments

The hydrogel also performs excellently in liquid environments. The copolymer chains contain both hydrophilic and hydrophobic units; after Fe³⁺ treatment, these segments migrate and rearrange on the surface, enabling strong adhesion in both water and oil. Using CIQTEK SEM3100, the team observed structural changes before and after Fe³⁺ soaking, confirming polymer network rearrangement. Studies on NIPAM and PTAs’ influence showed their combined effect yielded outstanding adhesion in dry, aqueous, and oily environments, with adhesion strengths reaching 121 kPa, 227 kPa, and 213 kPa, respectively. The hydrogel strongly adheres to various substrates, including glass, metal, and wood, and maintains good adhesion in multiple organic solvents and aqueous solutions.

Figure 4. Wet adhesion performance in various liquid environments.

Figure S10. SEM images of hydrogel cross-section before and after Fe³⁺ treatment showing network loosening.

Repair Performance on Damaged Materials

PANC/T-Fe hydrogel has broad application prospects for the temporary repair of damaged materials. For example, in boat model leak repair tests, the hydrogel quickly stops liquid leakage; the repaired boats withstand certain weights without leakage. When repairing damaged substrates in water and oil, the hydrogel endures maximum burst pressures of 57 kPa and 49 kPa, respectively. Ice application allows easy removal without residue, a valuable feature for biomedical and smart material applications, demonstrating great practical potential.

Figure 5. Temporary repair performance of PANC/T-Fe hydrogel.

This study successfully synthesized PANC/T-Fe hydrogel featuring strong adhesion in various environments and reversible on-demand adhesion. It elucidated how dynamic interchain interactions influence adhesion performance, providing theoretical guidance for novel intelligent adhesive materials. The on-demand adhesion requires no external energy, achievable by ice application, offering a new approach for intelligent adhesives in liquid environments. This innovative control of adhesion performance is expected to enable broad applications and advance smart adhesive technologies, offering new solutions to adhesion-related challenges.

As the "blood vessels" and "nerves" of the automotive electronic and electrical system, the automotive wiring harness is the key network body that connects various electronic components, ECUs, sensors and actuators inside the vehicle, and is responsible for the transmission of power and signals. According to the voltage level, wiring harnesses are mainly divided into high-voltage wiring harnesses (with a voltage higher than 60V) and low-voltage wiring harnesses. The former has higher requirements in terms of temperature resistance, voltage resistance and anti-electromagnetic interference. Aichie provides customers with one-stop wiring harness services and can produce and customize all types of wiring harnesses: high-voltage wiring harnesses, low-voltage wiring harnesses, high-frequency and high-speed cables, automotive internal wire harness, energy storage wiring harnesses, industrial wiring harnesses, and electronic wiring harnesses, etc. As the automotive industry accelerates its development towards electrification, intelligence and connectivity, the technical requirements and market demands for wiring harnesses are undergoing profound changes, and their importance is increasingly prominent.

High-voltage wiring harnesses: A core incremental market in the wave of electrification

Against the backdrop of the accelerated electrification of the global automotive market, the demand for high-voltage wiring harnesses is experiencing explosive growth. Pure electric vehicles rely entirely on high-voltage batteries for power supply. Their battery capacity and motor power are usually larger, which puts forward higher requirements for the performance and value of high-voltage wiring harnesses. Compared with traditional fuel vehicles, the high-voltage wiring harnesses of new energy vehicles need to withstand higher voltages (usually 300V-800V) and larger currents, and also need to have excellent high-temperature resistance, corrosion resistance, and anti-electromagnetic interference properties. Therefore, the value per vehicle of high-voltage wiring harnesses has significantly increased, reaching 2,000 to 3,500 yuan, which is much higher than that of traditional low-voltage wiring harnesses. Aichie provides customers with high-quality and highly reliable high-voltage wiring harnesses for new energy vehicles and has cooperated with many well-known automakers to supply automotive wiring harnesses for them.

According to industry reports, the global market size of automotive high-voltage wiring harnesses reached 39.7 billion yuan in 2023. It is expected to increase to 48.4 billion yuan in 2024 and reach 99.8 billion yuan in 2030, with a compound annual growth rate (CAGR) of 14.1% during this period. This growth is mainly attributed to the rapid increase in the global penetration rate of new energy vehicles, especially the policy-driven and technological breakthroughs in the three major markets of China, Europe and North America. In addition, the gradual popularization of 800V high-voltage platforms has further raised the technical threshold and added value of high-voltage wiring harnesses, bringing new development opportunities to leading enterprises in the industry.

High-speed wiring harnesses: The future growth pole driven by intelligence

Meanwhile, the trend of automotive intelligence is driving a sharp increase in the demand for high-speed data transmission. As the level of autonomous driving evolves from L2 to L3/L4, the number of on-board sensors (such as cameras, radars, and lidars) has increased significantly, and the data transmission rate has also risen from 150 Mbps to 24 Gbps. This has given rise to the application of high-speed connectors and related wiring harnesses to meet the demands of low-latency and high-bandwidth data transmission.

The value of a high-speed wiring harness per vehicle is usually between 300 and 1,500 yuan, and it increases with the improvement of the vehicle's intelligence level and configuration. For instance, vehicles supporting autonomous driving systems require more high-speed data transmission channels to process real-time data from multiple high-definition cameras and millimeter-wave radars. The global market size of automotive high-speed wiring harnesses was 16.8 billion yuan in 2023. It is expected to expand to 27.8 billion yuan in 2024 and reach 81.6 billion yuan by 2030, with a CAGR as high as 25.3%. The growth rate far exceeds that of high-voltage wiring harnesses, demonstrating even more rapid growth potential.

The global competitive landscape: Dominated by Japan and the United States, Chinese enterprises are catching up at an accelerated pace

The global automotive wiring harness market has long been dominated by Japanese and American giants, among which the combined market share of Japanese manufacturers Sumitomo Electric and Yazaki exceeds 50%. Other enterprises such as Aptiv from the USA, Leoni from Germany, Samar from India and Lear from the USA also hold important positions. These international giants, relying on their technological accumulation, scale advantages and global layout, have long monopolized the high-end market, especially holding a dominant position in the field of high-voltage and high-speed wire harnesses.

In contrast, although the domestic wire harness market in China has a large number of manufacturers, its concentration and market share are relatively low, and there is huge room for improvement. Domestic wire harness enterprises can roughly be classified into four categories: independent wire harness factories (such as Kunshan Huguang and Tianhai Electronics), wire harness factories for automotive manufacturers (such as BYD's Fudi Wire Harness), foreign-funded factories (such as Sumitomo Electric's subsidiaries in China), and joint ventures (such as the joint venture between Aptiv and local enterprises). Overall, foreign-funded and joint venture enterprises still hold a dominant position. However, with the rapid advancement of China's automotive "three modernizations" (electrification, intelligence, and connectivity) and the rise of domestic auto brands, domestic wiring harness manufacturers are gradually increasing their market share through technological breakthroughs and cost advantages.

Connector: The key interface of the wiring harness system

At both ends of the wiring harness, connectors play a crucial role in connecting the wiring harness with electrical equipment. In the markets of automotive high-voltage wiring harnesses and high-speed wiring harnesses, the market share of connectors is expected to reach 55% and 65% respectively. The technical threshold and added value of connectors are even higher than those of the wiring harnesses themselves. High-voltage connectors need to meet the transmission requirements of high voltage and large current, and at the same time possess excellent sealing performance and shock resistance. High-speed connectors need to address the issues of loss and interference in the transmission of high-frequency signals, and have extremely high requirements for materials, structures and processes.

The global automotive connector market is also dominated by American and Japanese enterprises, with leading companies holding solid positions, including Tyco Electronics (Switzerland), Yazaki (Japan), Aptiv (USA), JAE (Japan Air Electronics), and Rosenberg (Germany), among others. These enterprises, relying on their first-mover advantages and technological barriers, have long monopolized the high-end market. However, in recent years, domestic connector manufacturers in China have made remarkable breakthroughs in the field of high-voltage and high-speed connectors. For instance, Suzhou Ruike Da has developed high-voltage and high-current connectors, AVIC Optoelectronics has provided liquid-cooled charging solutions, and Dianlian Technology has developed high-speed connectors for vehicles. With cost advantages and localized service capabilities, these enterprises are gradually promoting the process of domestic substitution and expanding overseas markets as Chinese vehicle manufacturers "go global".

Future: Driven by both technological upgrading and domestic substitution

As the automotive electronic and electrical architecture evolves from distributed to domain-centralized, the design of wiring harnesses and connectors will also tend towards integration and lightweight. For instance, Tesla's 48V low-voltage architecture and simplified wiring harness solution may become one of the future technological directions in the industry. For Chinese enterprises, seizing the historical opportunities of electrification and intelligence and breaking through the core technologies of high-voltage and high-speed wiring harnesses and connectors is the key to achieving a leapfrog development.

It can be foreseen that the global automotive wiring harness market will maintain a high growth rate in the coming years, and the share of Chinese manufacturers is expected to increase further. With the multiple impetus of policy support, industrial chain collaboration and technological innovation, domestic enterprises may achieve a leap from "following" to "keeping pace" or even "taking the lead" in high-pressure and high-speed fields.
