Electric‐field‐assisted spin coating is introduced as a wet‐film processing route for guiding perovskite crystallization. A transient perpendicular field produces distinct structural maxima rather than monotonic grain growth: largest scanning electron microscopy (SEM)‐derived grain size at nominal 2 kV cm−1${\rm cm}^{-1}$, largest X‐ray diffraction ...

A codesign multiobjective optimization framework was developed to enhance the morphology and controller of a snake‐like robot driven by artificial muscles. It improved planar locomotion, agility, and power efficiency. The approach optimized link geometry and controller gains, revealing that shorter muscles near joints and longer linkages maximize ...
