Micro‐Texturized and Ultra‐Soft Dry Electrode for Motion‐Artifact Tolerant and Long‐Term Stable Wearable Electrophysiological Monitoring

Small, EarlyView.
A highly conformal and adhesive dry electrode is developed using a micro‐textured carbon black/PDMS composite. By leveraging spontaneous surface roughness for enhanced mechanical interlocking and integrating a stretchable serpentine interconnector, the device achieves robust skin contact and low impedance.

Retrofitting of a listed brick and wood building using vacuum insulation panels on the exterior of the facade: Measurements and simulations [PDF]

, 2014
Many old listed buildings have an unsatisfactory thermal performance compared to the standards of today. The listing often limits the position and necessary thickness of an added insulation layer in the building envelope.

Evaluation of Moisture Ageing Status of Cross‐Linked Polyethylene Insulation in Power Cables at Different Temperatures

High Voltage, EarlyView.
ABSTRACT Cross‐linked polyethylene (XLPE) cables play an important role in power systems to transport electrical energy, and moisture is one of the important predisposing factors for insulation failure in medium and high‐voltage cables. In this paper, a temperature‐moisture accelerated ageing experiment is designed, and a method for assessing the ...

Combustion Performance of Silicone Rubber Polymer Insulation Material Under Damp‐Heat Ageing Conditions: Molecular Insights Into the Effects of Structural Changes on Macroscopic Properties

High Voltage, EarlyView.
ABSTRACT Silicone rubber (SR), an organic silicon polymer material, is known for its excellent heat resistance and mechanical properties. It is widely used in composite insulators and cable accessory materials. However, the ageing caused by humidity and heat significantly impacts its performance, an issue that cannot be ignored. This paper investigates

Engineered Interpenetrating MXene Networks in Aramid Layered Films for Antioxidant and Broadband Electromagnetic Interference Shielding

Advanced Science, Volume 13, Issue 18, 27 March 2026.
This study introduces an innovative interpenetrating layered structure, comprising alternating aramid nanofiber (ANF) layers and MXene layers, fabricated through a directional freeze–thaw intercalation–gel‐film formation strategy. Unlike traditional homogeneous layered films, this unique layered structure features mutually embedded conductive and ...
