Versatile Silicon‐Based Surface‐Enhanced Raman Spectroscopy Chip for Quantitative Sensing and Point‐of‐Care Applications

open access: yesAdvanced Materials Interfaces, EarlyView.
This study fabricates highly sensitive, uniform SERS substrates scalable to wafer level. The dual‐function substrates integrate high‐density hot spots and spectral references for accurate quantitative detection, achieving 10⁻¹2 M BPE sensitivity (<5% deviation). Their application in monitoring urinary caffeine citrate for preterm infant apnea treatment

High Aspect Ratio, Superconducting Vacuum Gap Capacitor NEMS with Plate Distances Down to 32 nm

open access: yesAdvanced Materials Technologies, EarlyView.
Fabrication of aluminium vacuum gap capacitor based NEMS is investigated with a free to move top electrode. To avoid collapse of the top electrode vertical stress gradient is controlled through sputter parameters. The result is wafer‐level high‐yield fabrication of vacuum gap capacitors with radii between 7 µm and 30 µm and integrated piezoactuators. A

Temperature‐Dependent Voltage Control of Flexible Polymeric Electrochromic Devices for Improved Durability

open access: yesAdvanced Materials Technologies, EarlyView.
The functionality of flexible polymeric electrochromic devices (ECDs) in high‐temperature environments is crucial for long‐term durability. The thermal stability of ECDs based on a poly(3,4‐ethylenedioxythiophene) derivate and Prussian blue is improved by analyzing the temperature‐dependent electrochemical behavior of the electrodes and the ECDs.
