A Versatile-Designable Framework for Active and Programmable Shape-Morphing Soft Matter Systems: From Inverse Design to Closed-Loop Control. [PDF]

open access: yesAdv Sci (Weinh)
A versatile framework integrates addressable electrothermal actuation and strain‐constraint mechanisms to construct programmable shape‐morphing soft matter systems. By combining an analytical inverse design strategy for high‐fidelity 3D surface reconstruction with deep learning‐based closed‐loop control, this approach enables zero‐energy shape locking,
