Sedentary lifestyles and evolving work environments have created challenges for global health and cause huge burdens on healthcare and fitness systems. Physical immobility and functional losses due to aging are two main reasons for noncommunicable disease mortality. Smart electronic textiles (e-textiles) have attracted considerable attention because of their potential uses in health monitoring, rehabilitation, and training assessment applications. Interactive textiles integrated with electronic
A highly flexible and transparent conductive electrode based on consecutively stacked layers of conductive polymer (CP) and silver nanowires (AgNWs) fully embedded in a colorless polyimide (cPI) is achieved by utilizing an inverted layer‐by‐layer processing method. This CP‐AgNW composite electrode exhibits a high transparency of >92% at wavelengths of 450–700 nm and a low resistivity of 7.7 Ω ◻ −1 , while its ultrasmooth surface provides a large contact area for conductive pathways.

A new approach to the fabrication of a transparent, stretchable and pressure-sensitive capacitor was developed by employing a single layer of Ag nanowire-based electrodes and a transparent, stretchable polymer.
Crack-based strain sensor systems have been known for its high sensitivity, but suffer from the small fracture strain of the thin metal films employed in the sensor which results in its negligible stretchability. Herein, we fabricated a transparent (>90% at 550 nm wavelength), stretchable (up to 100%), and sensitive (gauge factor (GF) of 30 at 100% strain) strain gauge by depositing an encapsulated crack-induced Ag nanowire (AgNW) network on a hydroxylated poly(dimethylsiloxane) (PDMS) film. Str
A transparent electrode comprising Ag nanowires and a polyurethane equipped with Diels–Alder adducts as crosslinkers was successfully fabricated to realize a rapidly amendable electrode.
A stretchable and photo-induced healable transparent electrode is achieved by using a combination of silver nanowires and thermoplastic polyurethane.
