Summary: Transparent microelectrodes have been widely studied in the biomedical field due to their advantages in simultaneous electrical and optical interrogation of cell/tissue activity. In this study, a microelectrode array (MEA) with gold-coated silver nanowires (Au-Ag NWs) was designed to achieve desirable mechanical stretchability, optical transparency, electrochemical performance, and chemical stability. The MEAs exhibited high optical transparency, low electrochemical impedance, stable chemical and electromechanical performance, and superior capability for colocalized electrophysiological and optical mapping of cardiac function.

Summary: Silver nanowires (AgNWs) are promising materials for transparent conductive electrodes in optoelectronic devices, but their practical use is hindered by corrosion under ambient conditions. This study presents a novel approach using a transparent synthetic rubber, TBR, as a stretchable substrate and a protective gas barrier, which effectively prevents corrosion and enhances the durability of AgNW networks.

Summary: In this study, novel junction-free 2D web-in-web Au conductors were fabricated with excellent stretchability and transparency. Computer fluid dynamics simulation was first performed to evaluate the potential 2D mesh structures. The optimized web-in-web network, consisting of symmetric large voids and asymmetric small voids, achieved up to 70% stretchability without a significant increase in sheet resistance and maintained high transparency. This research paves the way for replacing conventional ITO electrodes in next-generation stretchable optoelectronic devices.

Summary: In this paper, a multiscale analysis method is proposed to simulate carbon nanoparticles (CNPs)-filled polymers as strain sensors in wearable electronic devices, flexible skin, and health monitoring. A microscale representative volume element model of the CNPs-filled polymer is established based on the microstructure characteristics using the improved nearest-neighbor algorithm. The resistance variation of the CNPs-filled polymer with strain is obtained by considering the composite as a circuit network composed of vast random resistors determined by the junction widths between adjacent aggregates. Numerical and experimental investigations show good agreement, verifying the proposed method's effectiveness in predicting the electromechanical behavior of CNPs-filled polymers with different material parameters.
