Responsive Materials, EarlyView.We reported a stress‐guided photo‐programming strategy that enables cholesteric liquid crystal elastomers (CLCEs) to achieve synchronous 3D shape morphing and structural color evolution from a single 2D film. Abstract Flexible materials with dynamic structural colors have attracted considerable interest for multilevel information interaction, showing ...

Responsive Materials, EarlyView.We systematically summarize how each scale dictates fundamental choices in design feature, manufacturing technology, driving mechanism, and control strategy, which are inherently governed by scale‐dominated physical principles. Furthermore, the application of scale‐determined operation modes of microrobots across different stages of medical ...

Small, EarlyView.A spray‐drying‐based synthesis enables the formation of zinc ferrite nanoparticles with customizable induction heating from room temperature to 250°C by varying the zinc content and postsynthesis annealing temperatures. The aqueous dispersions are colloidally stable and heat up to biologically relevant thresholds. Hence, this approach offers a scalable

, 2016 A new simulator, ContactLess Simulator (CLS) has been developed in Visual C#. It is thus easy portable; several windows permit the user to configure the whole electronic system and to launch the simulation. It is specifically written to simulate contactless-powered smart systems, such as Near Field Communication (NFC) coupled to a microcontroller unit (
