      abstract     = {Stretchable hydrogel microfibers as a novel type of ionic
                      conductors are promising in gaining skin‐like sensing
                      applications in more diverse scenarios. However, it remains
                      a great challenge to fabricate coating‐free but
                      water‐retaining conductive hydrogel microfibers with a
                      good balance of spinnability and mechanical strength. Here
                      the old yet significant redox chemistry of Fe‐citrate
                      complex is employed to solve this issue in the continuous
                      draw‐spinning process of poly(acrylamide‐co‐sodium
                      acrylate) hydrogel microfibers and microfiber nets from a
                      water/glycerol solution. The resultant microfibers are
                      ionically conductive, highly stretchable, and uniform with
                      tunable diameters. Furthermore, the presence of
                      redox‐reversible Fe‐citrate complex and glycerol endows
                      the fibers with good anti‐freezing, water‐retaining, and
                      environmentally intelligent properties. Humidity and UV
                      light can finely mediate the stiffness of hydrogel
                      microfibers; conversely, the ionic conductance of
                      microfibers is also responsive to light, humidity, and
                      strain, which enables the highly sensitive perception of
                      environmental changes. The present draw‐spinning strategy
                      provides more possibilities for coating‐free conductive
                      hydrogel microfibers with a variety of responsive and
                      sensing applications.},
