Cell‐Stress‐Free Percutaneous Bioelectrodes

open access: yesAdvanced Materials, EarlyView.
A structurally adaptive soft microneedle bioelectrode is developed with an effervescent sacrificial core that dissolves after insertion, leaving an ultrathin and highly compliant electrode integrated with skin. This design enables ultra‐flexible, cell‐stress‐free, stable, and high‐fidelity electrophysiological monitoring under dynamic conditions such ...

Engineering Electrical Transport by Implantation‐Induced Defects in CrN Films Without Affecting Thermal Conductivity

open access: yesAdvanced Materials Interfaces, EarlyView.
This study demonstrates how implantation‐induced defects in CrN thin films enable controlled tuning of electrical transport from metallic to semiconductor‐like behavior while preserving thermal conductivity. Through cumulative argon implantation, defect landscapes are engineered to manipulate carrier mobility and conduction mechanisms, revealing key ...
