Draft:FibeRobo

  • Comment: The first sentence, and the fact that it was developed in 2023 makes this unsuitable for Wikipedia. It is certainly too soon to be considered. I urge you not to try and resubmit for some years until (iff) it is proven. Otherwise I recommend rejection without the possibility of revising. Ldm1954 (talk) 02:15, 11 December 2023 (UTC)
  • Comment: Needs sources that talk about the subject that aren't by MIT folks. Stuartyeates (talk) 08:02, 30 November 2023 (UTC)
  • Comment: Still reads like an advert with inappropriate language throughout.
    All your sources are still primary or connected in some way with the project. We need secondary sources. Qcne (talk) 11:01, 27 November 2023 (UTC)

Introduction edit

FibeRobo is an experimental smart fiber made from liquid crystal elastomers (LCEs) recently developed for creating shape-changing textiles.[1] LCEs show promise for introducing stimulus response capabilities into fabrics, but earlier attempts faced limitations in areas like responsiveness, durability, and compatibility.[2]

History edit

Developed at MIT in 2023 as a thermally-triggered smart material for creating shape-changing and interactive textiles. Inspiration stemmed from seeking to improve limitations around responsiveness, durability and compatibility faced by predecessor fibers, like twist-coiled polymers and shape memory alloys without sacrificing effectiveness or manufacturability.[3][4] Goals included balancing key properties in a single fiber, guided by principles of integrated interactivity, process compatibility and customizable morphology.[5]

Composition and fabrication process edit

FibeRobo tries to balance key properties using an acrylate/thiol polymer matrix with embedded liquid crystals, enabling both elasticity and heat sensitivity for reversible deformation uncommon in standard fibers.[6] A specialized melt-spinning process can continuously draw the FibeRobo resin into filament at production scales.[7]

Properties and mechanism edit

Heating FibeRobo above 30-60°C temperatures disrupts the liquid crystal alignment, enabling up to 40% contraction of the polymer chains, which fully reverses upon cooling.[8] Characterization shows sub-10 second response times over 100 cycles with minimal performance deterioration. The sub-millimeter diameters also allow integration into woven and knitted textiles without jamming.[9]

Implementation examples edit

Early FibeRobo prototypes exhibit capabilities for precise heat-triggered shape change when embedded into fabrics. Example applications include morphing bras with support customized by body patterns, transforming lampshades, curtains, and canine compressive jackets designed to tighten around the torso.[9]

Current adoption outlook edit

Researchers believe FibeRobo’s natural muscle-like capabilities could enable applications in soft robotics, haptics, and interactive architectures. However, transitioning innovative materials like FibeRobo into commercial products requires surmounting extensive development and safety validation hurdles.[10]
