In the interactive world of electronic devices, the split between professional drawing and daily touch has long been an insurmountable chasm in the industry. Hanvon Technology's global first magnetic-capacitive dual-mode touch chip HW0888, developed over seven years, ends the dilemma of "having to choose between fish and bear's paw" with its disruptive single-chip architecture, redefines the future form of human-computer interaction, and slims down and reduces costs for ePaper handwriting devices.
### Subverting Tradition: The Qualitative Change from "Technological Split" to "Single-Chip Integration"
In traditional touch technologies, the high-precision pressure sensitivity of electromagnetic pens and the convenient operation of capacitive screens were like two parallel lines - the former is a "professional necessity" for designers and creators, but is limited by thick devices and inability to use finger touch; the latter is a "daily standard" for mass users, but struggles to meet professional standards in pressure sensitivity and battery life.
In 2018, Hanvon Technology keenly captured this pain point, formed a technical team led by Xiang Guowei, and launched the R&D journey of "magnetic-capacitive integration". After seven years of tackling difficulties, HW0888 made its debut in 2025, realizing the coexistence of electromagnetic pen and capacitive touch on a single chip for the first time: no need for independent IC stacking or tedious switching, a passive electromagnetic pen and finger touch seamlessly collaborate, making "precise creation" and "convenient operation" perfectly compatible on the same ePaper handwriting device.
### Three Core Breakthroughs: Rewriting the Rules of Touch Technology
▍Single-Chip Dual-Mode Architecture: Triple Innovation of Space, Cost and Experience
HW0888 uses a high-performance metal mesh sensor, integrating electromagnetic induction coils and capacitive electrodes into a 0.3mm ultra-thin film layer, saving 50% of internal space and reducing material costs by 30% compared with traditional solutions. The built-in DSP (digital signal processor) in the chip acts as a "smart butler", real-time distinguishing signals between the electromagnetic pen (20kHz frequency band) and finger touch (100-300kHz frequency band), with switching delay less than 1 millisecond - whether it is the delicate pressure sensitivity of a designer's stroke or the smooth operation of daily zooming and sliding, it can be seamlessly connected. The dynamic resource allocation technology allows the chip to "work on demand": when an electromagnetic pen is detected, it prioritizes processing high-precision pressure data; when entering a multi-touch scenario, it instantly optimizes the capacitive signal response, truly achieving "dual-tasking".
▍Passive Electromagnetic Pen: "Invisible Evolution" of Professional Creation Experience
Continuing Hanvon's 25 years of electromagnetic touch technology accumulation, the passive electromagnetic pen of HW0888 is a "creation artifact": 8192 levels of pressure sensitivity with an accuracy of ±0.1g, which can accurately restore everything from hair-thin lines of a light pencil stroke to block textures of a heavy marker stroke; the pen body does not need a battery, only 9 grams ultra-light design, 40% lighter than mainstream active capacitive pens, and no burden for long-time holding; ±60-degree tilt recognition function simulates the side edge of a real brush, whether it is the natural transition of watercolor晕染 or the virtual-real change of sketch排线, it can be easily presented, making digital creation infinitely close to the touch of real paper and pen.
▍Anti-Interference Black Technology: "Steady as a Rock" in Complex Environments
In the extreme test in Huaqiang North, Shenzhen, HW0888 maintained 99.9% touch accuracy rate in the face of multiple interferences such as mobile phone signals, Wi-Fi and wireless charging. This benefits from its "hardware + software" dual protection system: at the hardware level, four-layer PCB board with special shielding layer and differential signal transmission technology isolate clutter from the physical level; at the software level, adaptive filtering algorithm and machine learning model "purify" signals in real time, dynamically adjust the sampling frequency to avoid interference frequency bands, and ensure stable operation even in complex scenarios such as factory workshops and exhibition sites.
Full-Scene Empowerment: "Interactive Revolution" from Consumer Electronics to Industry Applications
▍Consumer Electronics: "Two-Way Run" of Thinness and Functionality
- **ePaper Handwriting Notebooks**: The magnetic-capacitive co-body design reduces the thickness of the device by one layer of electromagnetic handwriting board, and the cost is also saved by more than 20 US dollars, taking into account both finger touch and electromagnetic professional writing experience, and can easily handle both meeting records and hand account creation.
Premium Tablets: After a domestic flagship tablet is equipped with HW0888, the thickness is reduced by 15%, and the battery life is increased by 20%. Designers can smoothly carry out professional-level illustration creation, while students can switch to the note-taking mode with one click, and have no pressure to watch dramas and entertain after class. 
Foldable Smartphones: In the unfolded state, the electromagnetic pen becomes a "mobile drawing board", supporting precise annotation and handwriting input; when folded, the multi-finger touch function seamlessly takes over, and operations such as games and web browsing are smooth, with a mis-touch rate as low as 0.5%.
▍Education Industry: "Efficiency Hub" of Smart Classrooms
In the intelligent classroom of a key school in Beijing, HW0888 supports 4 electromagnetic pens writing simultaneously and 10-point capacitive touch. Teachers can write formulas on the blackboard while operating multimedia courseware, and students can submit answer results through capacitive touch, with the system recognition rate increased to 98%. Classroom interaction is more efficient and knowledge transfer is more intuitive.
▍Industrial Control: "Productivity Champion" in Harsh Scenarios
In the field of intelligent manufacturing, HW0888 shows "hardcore strength": supports gloved operation, adapts to factory environment; electromagnetic pen can be used for precise drawing annotation, and pressure sensitivity meets industrial-grade requirements; anti-interference ability passes industrial-grade EMC standard certification, and can stably complete equipment debugging, data entry and other operations even in strong electromagnetic environments.
The Future is Here: When Technological Innovation Meets "Humanism"
Hanvon Technology's exploration of HW0888 has not stopped at the present: the next generation of products will integrate AI accelerators to achieve functions such as stroke prediction and intelligent gesture recognition, making interaction better understand user needs; the application of graphene sensors and self-healing materials will further improve sensitivity and durability. At the same time, Hanvon is taking the lead in formulating industry standards and cooperating with car companies and medical equipment manufacturers to promote the extension of magnetic-capacitive touch technology to scenarios such as in-vehicle interaction and medical electronics.
In essence, the value of HW0888 far exceeds the technical breakthrough itself - it accelerates the process of education digitization, provides a more friendly interaction mode for people with disabilities, and frees the creative industry from equipment constraints. As Xiang Guowei, General Manager of Hanvon Technology, said: "True technology is to let complex technology hide behind the scenes and let simple experience become the protagonist." HW0888 interprets the temperature and strength of "Chinese smart manufacturing" with the persistence of seven years of sharpening a sword - not for showing off skills, but for making every touch a beautiful beginning of dialogue between people and technology.
When the magnetic-capacitive touch technology opens a new chapter, we look forward to seeing more "impossibles" become "possibles", so that technology can truly return to and serve people.
