AB  - Designing autonomously oscillating materials is highly desirable for emerging 
      smart material fields but challenging. Herein, a type of hypercrosslinked 
      metal-organic polyhedra (HCMOPs) membranes formed by covalent crosslinking of 
      boronic acid-modified Zr-based MOPs with polyvinyl alcohol (PVA) are rationally 
      designed. In these membranes, MOPs serve as high-connectivity nodes and provide 
      dynamic borate bonds with PVA in hypercrosslinked networks, which can be 
      broken/formed reversibly upon the stimulus of water vapor. The humidity response 
      characteristic of HCMOPs promotes their self-oscillating and self-healing 
      properties. HCMOP membranes can realize a self-oscillating property above the 
      water surface even after loading a cargo that is 1.5 times the weight of the 
      membrane due to the fast adsorption and desorption kinetics. Finally, the HCMOP 
      actuator can realize energy conversion from mechanical energy into electricity 
      when coupled with a piezoelectric membrane. This work not only paves a new avenue 
      to construct MOP-polymer hybrid materials but also expands the application scopes 
      of MOPs for smart actuation devices.
