Flexible Microneedle Array Electrode with Improved Comfort, Low Impedance, and High Performance for Electrophysiological Recording.

High-fidelity electrophysiological recording is critical for wearable brain-computer interfaces and human-machine interaction. However, balancing signal quality and wearing comfort remains a challenge: wet electrodes suffer from gel dehydration, whereas conventional dry electrodes often exhibit high impedance and mecha...

Mechanically Robust, Self‐Healable, and Cryotolerant GelMA Hydrogel for Wearable Tactile Sensors with Enhanced Durability, Lifetime, and Environmental Stability

ABSTRACT Gelatin methacryloyl (GelMA) hydrogels are promising for wearable tactile sensors due to their biocompatibility, tissue‐mimic softness and conductivity, yet restricted by mechanical property, structure damage, dehydration, and freezing during usage. Herein, a mechanically robust, self‐healable, moisturizing, c...

Theoretical modeling and optimization design of T-shape cavity CMUTs for enhanced acoustic performances and lowered bias voltage

Capacitive micromachined ultrasonic transducers (CMUTs) are key components of ultrasonic technology, which have broad applications in medical, industrial, and military fields. The theoretical model enables rapid analysis of their electromechanical performances, which in turn guides the iterative design of CMUTs arrays....
