Multifunctional monolithic gold nanowires for wireless smart wearable personalized healthcare device.

Despite extensive investigation on soft bioelectronic systems for smart healthcare, it remains a big technical challenge to achieve robust, wireless integration of multifunctional components via monolithic patterning. Here, we developed a wireless wearable healthcare device fabricated using bulk and hollow gold nanowires (Ag@AuNW and AuHNW) with distinct electrical properties. The strain sensor based on AuHNW showed high sensitivity (ΔR/R = 773.

Wireless Organic Light-Emitting Diode Contact Lenses for On-Eye Wearable Light Sources and Their Application to Personalized Health Monitoring.

On-eye optoelectronic systems can address unmet needs across various healthcare applications, including monitoring of physiological signals related to vision or other diseases. In this context, this work introduces wearable light sources that combine ultrathin organic light-emitting diodes (OLEDs) with contact lenses. As an illustration, we demonstrate their efficacy as a robust lighting solution for electroretinography (ERG).

Interfacing liquid metals with stretchable metal conductors.

Unlabelled: Highly stretchable conductors are essential components in deformable electronics. Owing to their high stretchability and conductivity, liquid metals have attracted significant attention for use as circuits and interconnections. However, their poor wettability to stretchable metal electrodes prevents the formation of stable electrical connections.
