Researchers at Harvard have demonstrated that the humble craft of knitting can be harnessed to create genuinely functional, shape-shifting fabrics.
By manipulating stitch patterns and material choices, they engineered textiles that snap decisively between distinct configurations.
Crucially, these fabrics do not merely change appearance; they perform mechanical work, altering their stiffness or exerting force on demand.
Scientists categorise such responsive materials as "smart textiles", a rapidly expanding area of research.
Given their intrinsic softness and pliability, the fabrics are particularly well suited to soft robotics, where rigid components are undesirable.
The same principles could yield adaptive garments that respond dynamically to the wearer's posture or environment.
In a clinical context, they might serve as supportive braces that flex naturally with the body rather than constraining it.
Above all, the study underscores how a centuries-old technique can be reconceived as a platform for advanced engineering.
