Enhanced Deformability Through Distributed Buckling in Stiff Quasicrystalline Architected Materials

open access: yesAdvanced Materials, EarlyView.
Quasi‐periodic metamaterials combine stiffness and large‐strain deformability, overcoming limitations of traditional stretching‐dominated periodic designs that are prone to global buckling instabilities and catastrophic layer collapses. By leveraging non‐uniform force chains, they achieve high isotropic stiffness, stable deformation, and remarkable ...

Fabricating Mass‐Producible High‐Performance Metaholograms Using Sol‐Gel‐Processed TiO2

open access: yesAdvanced Materials Interfaces, EarlyView.
Mass production of metaholograms on 6‐in. glass is achieved through nanoimprint lithography. TiO₂ sol‐gel is used as an imprint resist, exhibiting a high refractive index in the visible region. Through heat treatment at 600 °C, TiO₂ gel crystallizes into the anatase phase, allowing the fabrication of high‐resolution images with high optical efficiency.

The Rise of Refractory Transition‐Metal Nitride Films for Advanced Electronics and Plasmonics

open access: yesAdvanced Materials Interfaces, EarlyView.
Transition‐metal nitrides (TMNs) are exceptional materials with high stability, biocompatibility, and semiconductor integration, which have been extensively employed in various fields. However, the epitaxial growth of TMN films remains a challenge. The absence of high‐quality TMNs limits the understanding of their condensed matter physics and hinders ...

A Sleeve Alters the Pressure‐Stretch Curve of a Hyperelastic Balloon to Enable Pre‐Programmed Sequencing

open access: yesAdvanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
This article demonstrates that encasing a hyperelastic balloon in an inextensible sleeve greatly increases its burst pressure. This simple mechanical behavior can be used to produce an asymmetric inflation‐deflation sequence for coupled balloons with different thicknesses so they could serve as a soft robot's rear and front anchors when driven from a ...

Photonic Crystal Enhanced Microscopy on a 2D Photonic Crystal Surface

open access: yesAdvanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
This work demonstrates the design, fabrication, and the first‐time test of a 2D photonic crystal surface for photonic resonator absorption microscopy. The designed surface uniformly enhances electromagnetic near fields, achieving > 100% improved detecting uniformity for surface‐captured AuNPs from a blocking biosensor assay aimed for detecting SARS‐CoV‐

Anti‐Counterfeiting Tags with Camouflaged QR Codes on Nanocavities, Using Polymer‐Dispersed Liquid Crystals

open access: yesAdvanced Materials Technologies, EarlyView.
A QR code, printed through a commercial printer on a thin plastic foil, pre‐coated with a nanocavity is proposed as an anti‐counterfeiting label. Nanocavity imparts distinctive optical properties in terms of light reflection and transmission. A thin layer of polymer‐dispersed liquid crystals (PDLC) is used to camouflage the QR code, that become ...

Electrical Metamaterial‐Based Interconnects‐Enabled Highly Stretchable Wireless Electrocardiography Circuit

open access: yesAdvanced Materials Technologies, EarlyView.
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 ...
