Scalable Fabrication of Chemically Stabilized Gelatin Hydrogel Fibers by Thermal Drawing
Scalable processing of hydrogel fibers remains a major challenge. By coupling thermal drawing with Maillard chemistry, a transient viscous‐flow window is created that enables continuous fabrication of microstructured gelatin fibers tens of meters long, while continued in situ crosslinking during drawing stabilizes the fibers for physiological ...

Skin‐Like Tri‐Modal Sensors Based on Soft Piezoelectric and Ionic Composites
Inspired by the multimodal perception of human skin, a soft, skin‐like tri‐modal sensor is presented. The device incorporates an ionically conductive, piezoelectric, elastic composite as its active layer, enabling independent detection of temperature, static strain, and dynamic strain within a single two‐terminal architecture.

Wood‐Derived Nanocellulose‐Biocarbon Fresnel‐Zone Plate Lenses for Sub‐THz Frequency Applications
Wood‐derived nanocellulose and lignin‐based biocarbon were combined to fabricate fully bio‐based Fresnel zone plate (FZP) lenses for sub‐terahertz frequencies. These sustainable FZP lenses exhibit low dielectric loss and high directivity, achieving performance comparable to that of metallic references, and remain functional under environmental stress ...

We introduce a novel method combining microfluidics, optogenetics, and human induced pluripotent stem cell (iPSC) technology to encapsulate single iPSC‐derived cardiomyocytes (iPSC‐CMs) in an optimal environment for functional characterization. This method enables direct genotype‐phenotype correlation for genetic studies and high‐throughput screening ...

Liquid Crystal Elastomer Actuator Matrix for Large Area Applications
A scalable approach is used to manufacture a digitally‐controllable, 2D 5 × 5 actuator matrix. The elements of the matrix are produced by direct ink writing of a liquid crystal elastomer ‘artificial muscle’ on large‐area flexible thin‐film heaters. In optimizing the low‐power actuators, multiple heater designs and substrate materials are investigated ...

3D‐Printed Actuator Powered by Liquid Crystal Elastomer Muscles at the Water–Air Interface
Soft robots for unstructured environments require responsive, durable actuators. Liquid crystal elastomers (LCEs) provide large reversible deformations under thermal or optical stimuli. Direct ink writing enables fabrication of LCE actuators integrated with silicone, with mesogen chemistry and oligomers optimized for printable inks.

Characteristics of pervasive learning environments in museum contexts [PDF]
There is no appropriate learning model for pervasive learning environments (PLEs), and museums maintain authenticity at the cost of unmarked information. To address these problems, we present the LieksaMyst PLE developed for Pielinen Museum and we derive
