Dynamic Liquid Gating Artificially Spinning System for Self-Evolving Topographies and Microstructures.

摘要: Developments in spinning systems have triggered revolutions ranging from bioengineering tissue scaffolds to emerging smart wearable fabrics, but the structures of fibers are usually limited by intrinsic channel configurations and "dead" nozzle's geometry. In contrast, natural living systems, such as a spider apparatus, use "live" gate coordinate microstructures via shearing expanding at both axial radial directions. Herein, for first time, we introduce dynamic liquid gating effect artificial mimic biological organisms. Theoretical modeling experimental regime diagram demonstrate that topographies self-evolve after passing through they could be tuned over wide range, which successfully exceeds limits current channels. particular, with periodic spindle-knot structure water show fast directional collecting intelligent sensing ability. The design not only sheds new light on fiber control multiple spatiotemporal dimensions also contributes development high-performance sophisticated functions.
