Micropatterned Biphasic Printed Electrodes for High‐Fidelity on‐Skin Bioelectronics

Advanced Functional Materials, EarlyView.
Micropatterned biphasic printed electrodes achieve unprecedented skin conformity and low impedance by combining liquid‐metal droplets with microstructured 3D lattices. This scalable approach enables high‐fidelity detection of ECG, EMG, and EEG signals, including alpha rhythms from the forehead, with long‐term comfort and stability.

Microplastics from Wearable Bioelectronic Devices: Sources, Risks, and Sustainable Solutions

Advanced Functional Materials, EarlyView.
Bioelectronic devices (e.g., e‐skins) heavily rely on polymers that at the end of their life cycle will generate microplastics. For research, a holistic approach to viewing the full impact of such devices cannot be overlooked. The potential for devices as sources for microplastics is raised, with mitigation strategies surrounding polysaccharide and ...

Electromechanical Anisotropy in Aligned Nanomesh Electrodes for E‐Skin Applications

Advanced Materials Interfaces, EarlyView.
Aligned nanofiber mesh electrodes exhibit direction‐dependent electromechanical responses when strained along or across the fiber axis. This controlled anisotropy enables the same free‐standing device to function as either a high‐sensitivity strain sensor or a stretchable interconnect, offering a breathable and biocompatible platform for skin ...
