Balancing Design and Functionality
“Millimeter‑Wave Transparent Ag Coating” is our proprietary technology that allows millimeter‑wave signals to pass through while preserving a beautifully mirror‑like finish.
Beyond classic mirror styling, the lineup expands to matte, deep‑black, and other sophisticated design expressions.
Conventional plating blocks radio waves because its metallic decorative layer acts as a shield. In contrast, our newly developed technology achieves both premium aesthetics and full millimeter‑wave radar performance. For sensors operating in the mainstream 77 GHz band, transmission loss is kept to below 1 dB, ensuring exceptional signal clarity.
This coating makes it possible to conceal sensors entirely, delivering a refined exterior design while simultaneously enhancing functionality. The photo on the right—captured outdoors with the sky reflected—shows that its brightness level matches that of traditional plating, achieving a high‑grade visual quality.
Exceptional Reliability and Consistent Performance
This is a breakthrough technology that minimizes signal attenuation, ensuring stable millimeter‑wave radar performance while delivering refined, high‑end aesthetics.
Environmental Responsibility
This is engineered with a chromium‑free, rare‑metal‑free material design and a fully water‑based coating process, dramatically reducing resource consumption and environmental impact.
This approach enables environmentally conscious development and manufacturing across the entire product lifecycle, directly supporting our sustainability goals.
Application Scenarios
Application to Rear-View Mirrors (Occupant Detection & Child‑Presence Prevention)
By integrating millimeter‑wave sensors into the rear-view mirror, the system can precisely detect occupant position and posture, as well as child presence and vital signs such as heart rate and breathing.
Because millimeter‑wave sensing works even through clothing or blankets, overall safety is significantly enhanced. And with the “Millimeter‑Wave Transparent Ag Coating,” next‑generation in‑cabin sensing becomes possible without compromising the mirror’s aesthetic design.
Applications in Consumer Products & Home Equipment
“Millimeter‑Wave Transparent Ag Coating” enables millimeter‑wave sensors to be fully concealed without compromising the metallic design aesthetic, allowing advanced sensing capabilities to be embedded into a wide range of devices—from smart home appliances to bathroom mirrors.
It supports non‑contact monitoring of room occupancy, intrusion detection, heart rate, breathing, and posture, making next‑generation smart homes possible through a seamless fusion of design and functionality.
We are currently advancing research and development toward full mass production of this technology, aiming for even greater performance and broader application possibilities.
To help shape a safer, more comfortable future in mobility and smart living, we remain committed to continuous technological innovation.
