Compliant Die Attach Process for High‐Conformity Integration of Ultra‐Thin Chips on Curved Surfaces

open access: yesAdvanced Materials Technologies, EarlyView.
A compliant die attach process is developed for bonding ultra‐thin silicon dies onto high‐curvature surfaces. Using FEM‐guided tool design and process optimization, the method achieves excellent surface conformity and minimal voids. This approach offers a reliable solution for next‐generation curved electronics, including LiDAR and wide field‐of‐view ...

High‐Transmission Mid‐Infrared Bandpass Filters using Hybrid Metal‐Dielectric Metasurfaces for CO2 Sensing

open access: yesAdvanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
This article presents a hybrid metal‐dielectric metasurface in transmission mode for mid‐infrared (MIR) spectroscopy. Composed of germanium on aluminium cylinders atop a calcium fluoride substrate, the metasurface achieves 80% transmission efficiency at λ = 2.6 µm with a narrow full‐width‐half‐maximum of 0.4 µm.

Unilateral Ankle‐Foot Exoneuromusculoskeleton with Balance‐Sensing Feedback for Self‐Help Telerehabilitation after Stroke

open access: yesAdvanced Robotics Research, EarlyView.
This study introduces a hybrid robot that integrates mechanical assistance by musculoskeletons (i.e., soft pneumatic muscle with rigid exoskeletal extensions), neuromuscular electrical stimulation, and vibrotactile feedback in a lightweight wearable mechatronic complex applicable to the paretic ankle–foot poststroke for gait restoration. The system can

Fluorescence Label‐Free Doxorubicin Sensor Using Polystyrene Sulfonate as a Synthetic Receptor in Whispering Gallery Mode Microresonators

open access: yesAdvanced Sensor Research, EarlyView.
The illustration showcases resonant optical microsensors for Doxorubicin (DXR) detection, using polystyrene sulfonate (PSS) as a synthetic receptor. PSS is deposited as a nanometer‐thick layer on fluorescent microparticles via layer‐by‐layer assembly. DXR‐PSS interaction is depicted, highlighting its effect on the sensor's resonant modes.

A Wireless Soft Optical Blood Sensor for Colonoscopy

open access: yesAdvanced Sensor Research, EarlyView.
This works presents an “add‐on” wireless soft optical blood sensor for the traditional colonoscopy. It can reliably detect bleeding behind the colonoscope's distal tip camera via optical absorption, without optical fibers, and wirelessly transmit data to the processor.

Label‐Free, Sensitive, and Direct Detection of Cardiac Troponin Biomarkers Using Frequency‐Locked Microring Resonators

open access: yesAdvanced Sensor Research, EarlyView.
A deployable, chip‐integrated approach to the detection of heart attack biomarkers is demonstrated using silicon photonic microring resonators combined with microfluidics. By applying the Pound–Drever–Hall frequency locking technique, sensor signals are measured with improved signal‐to‐noise ratio, applying this to real‐time, selective readouts.

Environmental Impacts and Cost Analysis of Perovskite Nanocrystals for Light‐Emitting Diode Applications

open access: yesAdvanced Sustainable Systems, EarlyView.
CsPbBr₃ colloidal nanocrystals synthesized via hot‐injection (HI) and microwave‐assisted (MW) methods exhibit excellent optoelectronic properties for LEDs. Although the MW route is more energy‐efficient and eco‐friendly in the lab, industrially, its environmental impacts are similar, but with lower costs.
