Wearable medical devices such as smart bracelets, portable ECG recorders, and flexible body measurement garments need to be worn close to the skin. This requires not only high-quality electromagnetic shielding but also lightweight, skin-friendly, and breathable fabrics that feel comfortable against the skin. Heavy, rigid shielding materials simply cannot meet these requirements. Ultra-thin plain-weave EMI shielding fabrics, with their extremely thin, soft, skin-friendly, and breathable properties, have become the preferred shielding substrate for wearable medical electronics.

Medical-grade custom-made ultra-thin plain-weave EMI shielding fabrics are woven from skin-friendly modified polyester microfibers. The conductive coating on the surface undergoes passivation and non-toxic treatment, passing skin irritation tests. Prolonged close-fitting wear does not cause itching, allergies, or discomfort. The fabric has uniform warp and weft pores, providing excellent breathability and sweat-wicking properties, preventing stuffiness and stickiness during daily wear. The ultra-thin structure conforms to the curves of the limbs, eliminating any feeling of restriction during limb movements such as raising arms and turning over. Simultaneously, the internal continuous conductive network isolates external power frequency electromagnetic interference, ensuring the accuracy of physiological signal acquisition such as ECG and blood oxygenation, and preventing external noise from causing data deviation.

The fabric can be sewn into products such as the built-in shielding layer of flexible body measurement garments, ultra-thin shielding sleeves for ECG leads, and shielding bags for the entire inner lining of portable monitoring devices. The lightweight material will not increase the weight of wearable devices. The fabric has excellent wash resistance; its shielding effectiveness only slightly decreases after dozens of washes, meeting the daily cleaning needs of wearable devices. With the rapid expansion of the health wearable electronics market, orders for ultra-thin medical-grade shielding fabrics are steadily increasing. Companies are continuously optimizing antibacterial and breathable formulas and constantly improving their material systems specifically designed for wearable scenarios.
