Abstract
En 中文
As a classic mechanical fastening system, zippers are widely used in applications ranging from daily life to biomedicine. Conventional zippers, however, have limited deformation compatibility due to their unidirectional zipping and nonstretchable interlocking mechanism, highlighting their insufficient structural adaptability in scenarios involving cross-connections or multi-directional dynamic deformation. Here, we report a crossed stretchable zipper that enables zipping in overlapping areas via a cross adapter, prevents structural failure through latch-slot and suture-joint mechanisms, and closes separated fabrics while maintaining stretchability. This design allows a two-dimensional mesh configuration without compromising the inherent stretching performance of the zipper, significantly enhancing flexibility and adaptability. In hemiplegia rehabilitation wearables, modularity based on the crossed stretchable zipper offers advantages in personalized deployment and conformability, highlighting its potential for the personalized and widespread development of wearable systems.
