Enhancing Ceramic Structural and Interfacial Properties via Micro‐Patterning and Macro‐Architectural Integration

open access: yesAdvanced Materials Technologies, EarlyView.
This study investigates how laser‐micromachined patterns enhance the interfacial and mechanical properties of bioinspired ceramic composites. The ±45° micro‐pattern significantly improved interfacial bonding and damage dissipation energy by 107%, while integrating micro‐ and macro‐designs increased energy absorption by 60%.

Fully Passive Electrochemical Oxygen Sensor Enabled With Organic Electrochemical Transistor

open access: yesAdvanced Materials Technologies, EarlyView.
A wireless oxygen sensor that operates with low power without batteries, using organic electrochemical transistors (OECTs) powered by near‐field communication (NFC) is presented. The sensor combines an oxygen‐permeable membrane and a gel electrolyte to detect oxygen in air and complex liquids, making way for sustainable sensor technologies.

Multi‐Stamping on Multi‐Prestrain (MSMP) Process for Multifunctional Wearable Bioelectronics with Optimized Electromechanical Properties

open access: yesAdvanced Materials Technologies, EarlyView.
A novel multi‐stamping on multi‐prestrain (MSMP) process is proposed, where sensor elements are transferred onto a substrate under different prestrains (0–150%) within a single integrated platform. This MSMP approach not only resolves the mismatch issue in stretchable wearable electronics, but also ensures that each sensor element exhibits optimal ...
