Magnetic Actuation Under DC and AC Fields of Thermoplastic Polyurethane With Strontium Hexaferrite
Magnetic thermoplastic polyurethane composites with strontium hexaferrite (SrFe12O19) are produced through a solvent‐free melt‐mixing technique. These composites display a magnetomechanical actuation mechanism, being able to deform (bend and twist) through DC and AC magnetic fields, showcasing their potential as a promising material for the fabrication

This study presents a microfluidic wet spinning technique for producing ultrathin, templated collagen sheets with hierarchical organization at the microscale. The aligned collagen sheets replicate strain‐stiffening behavior associated with native cardiovascular tissues, sup cell attachment and contraction, and enable biofabrication of load‐bearing ...

High Aspect Ratio, Superconducting Vacuum Gap Capacitor NEMS with Plate Distances Down to 32 nm
Fabrication of aluminium vacuum gap capacitor based NEMS is investigated with a free to move top electrode. To avoid collapse of the top electrode vertical stress gradient is controlled through sputter parameters. The result is wafer‐level high‐yield fabrication of vacuum gap capacitors with radii between 7 µm and 30 µm and integrated piezoactuators. A

This study examines a soft gripper with a NiTiCu6 Shape Memory Alloy (SMA) wire embedded in a graphene nanoparticle (GNP)‐functionalized PDMS matrix. Comparing GNP‐enhanced and plain elastomer prototypes, results show that GNPs improve cooling rates, accelerating release by 40%, but increase energy consumption in low‐current activations.

This article presents a novel strategy for creating highly stretchable wireless circuits using electrical metamaterial‐based interconnects (EMIs). Embedded in soft polymers and filled with liquid metal, EMIs uniquely reduce resistance under strain. A fully integrated ECG circuit demonstrates reliable performance under 100% stretch, offering a highly ...

Dual Resonant Plasmonic Infrared Pixels for Selective Optical Encoding
This study presents dual‐resonant plasmonic nanostructures for advanced optical encoding in the mid‐infrared. By optimizing plasmonic resonances in nano‐antennas within ring cavities, selective and simultaneous tunability in both the MWIR and LWIR regions is achieved.

How to Manufacture Photonic Metamaterials
Metamaterials boast applications such as invisibility and “hyperlenses” with resolution beyond the diffraction limit, but these applications haven’t been exploited in earnest and the market for them hasn’t grown much likely because facile and economical methods for fabricating them without defect has not emerged.
