      abstract     = {Stimuli-responsive actuators are candidates for the
                      development of soft robots due to their shape deformation
                      and environmental adaptation capabilities. Adaptation to
                      environmental stimuli not only enables complex shape
                      reprogramming but also benefits the recovery of mechanical
                      injuries of the soft actuators. Nevertheless, reports on
                      soft actuators that integrate shape-reprogramming and
                      injury-healing functions into a monolithic actuating
                      material through facile fabrication strategies remain
                      scarce. Herein, a stimuli-responsive and healable actuator
                      is developed via layer-by-layer casting of two
                      stimuli-responsive materials with complementary properties.
                      Upon specific stimulation, these two materials reorganize
                      their structural network at the nano- and microscales and
                      heal. The resulting actuator exhibits a robust
                      photo-responsive actuating strength due to the asymmetric
                      volumetric responses of the two layers. Importantly, the
                      whole actuator can be healed with the aid of a sequential
                      heating-humidifying–drying treatment, achieving excellent
                      healing efficiency in both mechanical strength $(72\%)$ and
                      actuating strength $(95\%).$ Moreover, the initial actuation
                      modes can be restored and diversified through humidifying or
                      heating-assisted welding procedures, respectively. This work
                      demonstrates a facile strategy to construct reprogrammable
                      actuators with healing and welding abilities stimulated by
                      two environmental stimuli and provides a platform for
                      developing adaptable materials to a changing environment.},
