Streamlined Inkjet‐Printing of Stretchable Organic Photodetectors
This work introduces stretchable photodetectors fully inkjet‐printed on stretchable substrates. It is demonstrated that printed stiff platforms effectively decouple strain from the stretched substrate and serve as a chemically resistant and mechanically rigid platform.

This study proposes a magnetoelastic strain sensor for highly deformed posture perception. The sensor can maintain stable sensing signal output under significant strain (200%) and at varying stretch rates (ranging from 1000 to 8000 mm min−1). The sensor design is simple and can be applied to soft robots and wearable devices.

This work presents a method to print multi‐layer elastomer structures containing liquid cavities, where the fluid is incorporated as part of the printing process by freezing it, thus avoiding the conventional final filling step. We demonstrate this process by fabricating and characterizing dense arrays of zipping electrostatic actuators.

Production of Parallel Aligned Nanofiber Rovings From Continuous Bundles
Continuous nanofiber rovings are produced via electrospinning. The integration of false twisting and drawing improved fiber properties. Optimized twisting increases fiber alignment and tensile strength. The drawing process reduces the average nanofiber diameter from 297 to 200 nm and decreases the standard deviation of alignment angles from 14.2° to 8 ...

Anticounterfeiting optical devices typically rely on random surface patterns revealed under IR/vis/UV light. Despite its security, this method suffers from the unavoidable deterioration of exposed superficial patterns. The proposed technique utilizes the high penetration depth and resolution of THz radiation to reveal submillimeter metallic patterns ...

Mimicking Symmetry‐Breaking Einstein Ring by Optical Lens
This article uses an optical lens to emulate the gravitational lensing effect and observe the Einstein ring (ER) patterns. The symmetry‐breaking ER, i.e., Einstein cross, is observed utilizing a rotation‐symmetry‐breaking hemi‐ellipsoid lens. Deformed Einstein cross patterns induced by noncollinearly alignment of the light source–lens–observer are ...
