We present elastomeric three‐dimensional (3D) microstructures fabricated via two‐photon polymerization (2PP) and post‐processed through wet etching, for quantifying nanonewton (nN)‐scale forces applied by healthy and diseased neural cells. The mechanically characterized free‐standing beam architectures enable measurement of traction forces of ...

We present SCIENCE, an in‐ear multimodal physiological monitor featuring two key innovations. Water‐triggered morphological expansion (a 2‐mm cylinder to a 9‐mm spindle) achieves conformal adaptation across complex canal geometries. Simultaneously, active biofouling mitigation disrupts cerumen barriers, reducing sensor‐skin impedance by 20%.

Metastable Polymers for Circular 3D Printing
3D‐printed polymers are usually permanent and hard to recycle. Here, metastable polymers are designed to fall apart on demand. A chemical trigger unzips the printed material back into its original building blocks within minutes at room temperature.

Ultrathin MXene/EMF composite foams achieve a specific shielding efficiency of 749.6 dB.dB·cm3$\mathrm{dB}\cdot {\mathrm{cm}}^{3}$/g, while the silver‐enhanced MXene/Ag/EMF reaches 81.4 dB shielding effectiveness at just 1.0 mm thickness. Both composites exhibit rapid Joule heating, retain stability up to 250∘C$^\circ{\rm C}$, and withstand 1000 ...

Supramolecular aggregation governs the interfacial adsorption, diffusion, and fixation of anthraquinone‐based vat dyes in meta‐aramid fibers. By correlating reduction chemistry, aggregate formation, and fiber microstructure, a multiscale mechanism for aggregation‐controlled dyeing is established, providing an effective strategy to suppress surface dye ...

Eutectic Gallium‐Indium as a Potential Non‐Toxic Replacement in Mercury Intrusion Porosimetry
A practical alternative to mercury intrusion porosimetry is presented using non‐oxidized eutectic gallium‐indium. An eGaIn Filling Station enables oxygen‐free preparation of standard penetrometers, and the resulting measurements faithfully reproduce pore‐size distributions and intrusion volumes measured with mercury across several standard reference ...

Hierarchical multi‐material TPMS lattices are engineered as flexible tactile sensors by combining soft and stiff elastomeric layers with a conformal conductive coating. The bilayer architecture delivers sensitivity at low pressures while maintaining a broad detectable range under large loads, enabling reliable pressure and vibration monitoring for ...
