Fluctuating Curvature and Actuation in 4D Printed Asymmetric Networks by Frontal Photopolymerization

Advanced Materials Interfaces, EarlyView.
Asymmetric polymer networks, fabricated by frontal photopolymerization (FPP), are shown to exhibit curvature oscillations associated with monomer‐solvent exchanges during development and drying. We introduce a theoretical model for such dynamic curvature fluctuations and demonstrate the fabrication of bistable switches and self‐propelled materials that

Direct Ink Writing 3D Printing of Recyclable and Thermally Stable Vitrimers

Advanced Materials Technologies, EarlyView.
Vitrimers hold great promise in additive manufacturing as defect‐insensitive, repairable, and recyclable feedstocks. A thin‐film additively manufactured process is developed for a high‐performance vitrimer that is difficult to process traditionally.

Ionic Liquid‐Enhanced 3D Printed Flexible Resin for Pressure‐Sensing Applications

Advanced Materials Technologies, EarlyView.
A 3D‐printed resin–ionic liquid (IL) composite forms gyroid ionotronic architectures showing dynamic ionic migration under compression. Impedance analysis reveals distinct frequency responses across three topologies at high IL concentrations.

Advanced Design for Weakly Coupled Resonators by Automatic Active Optimization

Advanced Materials Technologies, EarlyView.
An Automatic Active Optimization (AAO) strategy integrates machine learning predictors and genetic algorithms in a closed‐loop workflow. By iteratively expanding its dataset with new discoveries, AAO overcomes the limits of conventional methods. This approach finds superior microstructural designs beyond the initial sample space. We demonstrate this on
