Responsive Visible‐Wavelength Metasurfaces from Porous Silicon Based on Fano Guided‐Mode Resonance

open access: yesAdvanced Optical Materials, EarlyView.
The article introduces mesoporous silicon metasurfaces (pSi‐MS) supporting Fano guided‐mode resonances in the visible regime. By combining top‐down lithographic patterning of 2D gratings with bottom‐up electrochemical porosification, the approach realizes a new class of responsive metasurfaces, enabling highly sensitive and portable platforms for small

Structural Colors from Ultrathin Lignin Films

open access: yesAdvanced Optical Materials, EarlyView.
Thickness‐dependent structural colors in ultrathin lignin films generate a full visible palette, tuned simply by solution concentration and spin speed. Abstract Structural colors offer a sustainable alternative to toxic pigments and dyes, yet their realization from lignin, the most abundant aromatic biopolymer, has remained elusive.

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

Low‐Strain Flexible Ink‐Based Sensors Enable Hyperelastic Inflation Perception Via Geometric Patterning for Balloon‐Type Robots

open access: yesAdvanced Robotics Research, EarlyView.
Integrating proprioceptive capabilities in balloon‐type robots enhances safe human–machine interactions. Traditional pressure estimates are inadequate due to nonlinear relationships. Instead, embedding stretchable sensors effectively measures deformation. This design optimizes sensor geometry to minimize damage risks.

Vision‐Assisted Avocado Harvesting with Aerial Bimanual Manipulation

open access: yesAdvanced Robotics Research, EarlyView.
This work outlines the design and implementation of a bimanual aerial robot that employs visual perception and learning to detect, reach, and harvest avocados. A new gripper and fixer arm assembly is used to harvest avocados, while visual perception enables the detection of avocados and estimation of their position and orientation for determining ...
