A Hydrophilic Hollow Microneedle Platform for Sampling Interstitial Fluid and On‐Site Biomarker Detection

open access: yesAdvanced Materials Technologies, EarlyView.
This study presents a superhydrophilic 3D‐printed hollow microneedle patch for continuous interstitial fluid (ISF) extraction and on‐patch biomarker sensing. Combining projection micro‐stereolithography and chemical vapor deposition, high‐resolution microneedles with enhanced wettability are fabricated, enabling passive ISF uptake without external ...

Fiber Bragg Gratings with Micro‐Engineered Temperature Coefficients

open access: yesAdvanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
Fiber Bragg gratings (FBGs) are intrinsically responsive to temperature and strain simultaneously. In this research, low‐loss FBGs with micro‐engineered temperature coefficients are fabricated, utilizing refractive index liquid‐filled microchannels in the cladding.

Advancing All‐Day Passive Radiative Cooling Performance of 3D Anodized Aluminum Oxide Nanostructures on Aluminium

open access: yesAdvanced Optical Materials, EarlyView.
Advanced anodic aluminium oxide (AAO) nanostructures incorporate interconnections between the vertical pores, forming a 3D‐AAO nanonetwork that functions as a Bragg reflector. By varying the periodicity of the transverse channels, the light‐matter interaction can be tuneable to enhance their emissivity and passive radiative cooling performance across ...

Micromachined Double‐Membrane Mechanically Tunable Metamaterial for Thermal Infrared Filtering

open access: yesAdvanced Photonics Research, Volume 6, Issue 5, May 2025.
Herein, a mechanically tunable double‐layer plasmonic metamaterial leveraging the extraordinary optical transmission effect observed in subwavelength arrays of openings within thin metal layers is presented. The concept is experimentally validated by integrating the proposed metamaterial structure into an electrostatic parallel‐plate actuator to create

Beam Combining of a Tunable Tilted Quantum Cascade Laser Array

open access: yesAdvanced Photonics Research, EarlyView.
The four‐channel tilted waveguide with varying angles in the quantum cascade laser array, achieving a free tuning range of 100 nm and common‐aperture output simultaneously, is reported. The fabrication eliminates the necessity of electron‐beam lithography and is very promising for mass production in gas sensing industry.
