      abstract     = {Robust damage-tolerant hydrogel fibers with high strength,
                      crack resistance, and self-healing properties are
                      indispensable for their long-term uses in soft machines and
                      robots as load-bearing and actuating elements. However,
                      current hydrogel fibers with inherent homogeneous structure
                      are generally vulnerable to defects and cracks and thus
                      local mechanical failure readily occurs across fiber normal.
                      Here, inspired by spider spinning, we introduce a facile,
                      energy-efficient aqueous pultrusion spinning process to
                      continuously produce stiff yet extensible hydrogel
                      microfibers at ambient conditions. The resulting microfibers
                      are not only crack-insensitive but also rapidly heal the
                      cracks in 30 s by moisture, owing to their structural
                      nanoconfinement with hydrogen bond clusters embedded in an
                      ionically complexed hygroscopic matrix. Moreover, the
                      nanoconfined structure is highly energy-dissipating,
                      moisture-sensitive but stable in water, leading to excellent
                      damping and supercontraction properties. This work creates
                      opportunities for the sustainable spinning of robust
                      hydrogel-based fibrous materials towards diverse intelligent
                      applications.},
