Medical Scenario-enabled TCF
Adopting a trinity structure of high-transmittance TCF substrate + micron-scale pressure sensing array + medical-grade biocompatible coating, this solution integrates high-density pressure sensing units (pitch ≤ 2 mm) into a transparent conductive film with over 90% light transmittance.
The surface is coated with a medical-grade coating certified for biocompatibility under ISO 10993, achieving a breakthrough integration of three core functions:
transparent observation + accurate vital signs monitoring + high-efficiency electromagnetic shielding, fully meeting the stringent requirements of medical and healthcare scenarios.

Differentiating Advantages
Precise Adaptation to Medical Scenarios
- Perfectly fits observation windows in medical imaging rooms (e.g., CT, MRI rooms). While ensuring clear observation of patient status, its electromagnetic shielding function (shielding effectiveness ≥ 40 dB) blocks strong electromagnetic interference from medical equipment and preserves monitoring data accuracy.
- Compatible with wearable health monitoring devices (e.g., medical monitoring wristbands, sleep monitoring mats). The biocompatible coating is non-sensitizing to skin, enabling safe and comfortable long-term wear.
Multi-Function Synergy
Combines vital signs monitoring and electromagnetic compatibility.
The pressure sensing array accurately captures core data including:
The pressure sensing array accurately captures core data including:
- Heart rate: error ≤ 2 bpm
- Respiration rate: error ≤ 1 time/min
Monitoring does not interfere with the normal operation of medical imaging equipment.
With light transmittance ≥ 90% and low haze, it does not block the viewing field, solving the pain points of traditional monitoring devices: obstructed vision or high susceptibility to interference.

Medical-Grade Safety & Reliability
- Biocompatible coating certified under ISO 10993‑5 (cytotoxicity) and ISO 10993‑10 (skin sensitization), complying with medical material safety standards.
- The film features excellent disinfection resistance: withstands repeated wiping with 75% alcohol and chlorine-containing disinfectants (≥ 500 cycles) without degradation in electrical conductivity or sensing performance, supporting high-frequency disinfection in medical environments.
Technical Support
High-Sensitivity Sensing Design
Using nano-infiltration engineering to composite carbon nanotubes (CNT) and polyvinylidene fluoride (PVDF), a flexible pressure sensing array is fabricated.
- Sensing sensitivity: 0.35 kPa⁻¹ (0–10 kPa pressure range)
- Response time: ≤ 20 ms
It precisely captures weak chest fluctuations during respiration and pulse waves, ensuring high-precision vital signs monitoring.
Balanced Electromagnetic Shielding & Light Transmittance
Adopting a composite structure:
TCF substrate + ultra-thin silver mesh shielding layer + transparent conductive coating
TCF substrate + ultra-thin silver mesh shielding layer + transparent conductive coating
- Silver mesh line width & pitch: 500 μm
- Electromagnetic shielding effectiveness: ≥ 40 dB (frequency range: 100 MHz–3 GHz)without compromising optical transmittance.
Customized conductive adhesive ensures seamless lamination between layers, avoiding signal interference between the shielding layer and sensing array.
Medical-Grade Manufacturing Assurance
- Produced in a GMP Class 8 cleanroom with strict control of dust and microbial contamination.
- Biocompatible coating deposited via plasma polymerization, thickness controlled at 5–10 μm, ensuring biosafety without reducing sensing sensitivity.
- Finished products certified by third-party medical testing institutions, fully compliant with medical material application specifications.
