Abstract Microdevices that manipulate fluids to transport in a predefined direction and switch flow directions under temperature stimuli are fundamental the intelligent control of biomedical devices, thermal managements, lab‐on‐a‐chip, etc. Despite current advances controlling drop transport, amplitude liquid motion is still limited with low speed, not well controlled because pinning contact lines on surface defects. Learning from nature, here, two bioinspired principles derived peristome pitcher plant beak shorebird fused into composite, peristome–beak mimetic fabricated switching between uni‐ bidirections fluctuations. Significantly, deposited water can intelligently find path by itself temperature‐patterned surface. This smart would extend design multi‐integrations use medical, microfluidic, heat‐transfer systems.
