3. Cov khoom siv kho mob kho tau
Ua haujlwm kom ua tau: Hloov pauv, kev coj ua, kev saib xyuas biosigral.
Kev daws teeb meem:
Conductive kub yaj xov: CNT / TPU Composite Xov Paj nrog Resistivity<10 Ω/cm for ECG electrodes (e.g., Myant Skiin smart garments).
Siab-hnov cov ntaub qhwv: PVDF-coated hot melt yarn monitors edema or varicose vein pressure (sensitivity >5 PC / n).
4. Cov khoom siv kho mob kho tau
Ua haujlwm kom ua tau: Biocompatibility, kev pab txhawb kev kho tshuab, tshuaj tso tawm.
Kev daws teeb meem:
Helnia Kho Heleses: Plasma-treated PP hot melt yarn grafted with collagen for cell adhesion (porosity >70%, iso 10993-5).
Tshuaj-Eluting Fibers: Siv lub xov tooj cua zoo melt
2. Qhov tseem ceeb thev naus laus zis
Biocompatibility hloov kho:
Nto Grafting: Low-temperature plasma grafting of heparin or peptides reduces thrombosis risk (clotting time extended to >60 feeb).
Biomimetic Qauv: Nanofibers mimic mimic tim ECM los coj cov qia cell sib txawv.
Kom tsis muaj menyuam txawj yoog:
Gamma / irradiation: Tswj kev ua tau zoo ntawm 25 kgy (ISO 11137).
Ethylene oxide (EO) kev sib raug zoo: Porosity >50% kom paub tseeb Eo nkag thiab cov seem<1 ppm.
3D luam tawm thiab customization:
Fused Deposition Modeling (FDM): PA hot melt yarn prints orthopedic braces with flexural strength >80 MPA (piv txwv li, Unyq ua kom haum rau cov neeg mob caj qaum).
Bioprincting Scaffolds: Diffradable Kub Qhuav Xov Paj Xov Paj Txhawb 3D-luam tawm cov qauv khoom siv.
3. Kev Lag Luam Cov Qauv thiab Ua Raws
