In article number 1907377, Dong Wu, Li Zhang, and co‐workers print hydrogel micro‐flowers in the spatiotemporal domain via femtosecond laser direct writing. The 4D printed architectures can respond to environmental stimuli with high speed. Complex shape‐morphing with expansion, contraction, twisting, and curling can be achieved by the proposed biomimetic 4D printing of hydrogels at the microscale.
