Cold‐Sublimating Quasi‐Solid Additive Enables High Efficiency and Long Operational Stability Binary Organic Solar Cells

open access: yesAdvanced Energy Materials, EarlyView.
Cold‐sublimating quasi‐solid mDF acts as an in situ‐removable transient structuring agent that broadens solvent‐removal, accelerates intermediate crystallization, and tightens π–π stacking in PM6:L8‐BO OSCs. Offering residue‐free morphology control, mDF‐treated OSCs enable high efficiency and a markedly extended operational lifetime (T80 = 477 h ...

Enhancing Sensitivity across Scales with Highly Sensitive Hall Effect‐Based Auxetic Tactile Sensors

open access: yesAdvanced Intelligent Systems, Volume 7, Issue 3, March 2025.
Herein, a tactile sensor based on hall‐effect sensors with an auxetic structure, called Hall effect‐based auxetic tactile sensor (HEATS), is proposed. The change in magnetism resulting from the deformation of the auxetic structure is utilized for sensing.

A Soft‐Tip Hydraulically Steerable Catheter for Enhanced Flexibility and Safety in Vascular Interventions

open access: yesAdvanced Intelligent Systems, EarlyView.
This study introduces a hydraulically steerable catheter with a soft tip in vascular procedures. The steering soft tip achieves a minimal diameter of 2.6 mm and supports a 180° bend. Real‐time shape and position tracking, facilitated by segmentation and endpoint detection techniques, improves navigation.
