Integrated sensor-actuators with exciting functionalities, such as action self-sensing, position posture or active sensing, are promising for applications in biomedical device, human-machine interaction, intelligent self-protection devices, and humanoid robots. Despite recent progress, it remains challenging to achieve a macroscopical integrated sensor-actuator material system microstructures. To address this critical challenge, 4D printing bioinspired microstructure strategy is reported...

Membrane‐based materials with special surface wettability have been applied widely for the treatment of increasing industrial oily waste water, as well frequent oil spill accidents. However, traditional technologies are energy‐intensive and limited, either by fouling or inability a single membrane to separate all types oil–water mixtures. Herein, biomimetic monolayer copper (BMCM), composed multiscale hierarchical dendritic structures, is cleverly designed successfully fabricated on steel...
