摘要

Fibrous wearable electronics have attracted extensive attention owing to their light weight, flexibility, and human-friendly design, while they face the challenge of synergistic working of conductive components with stable performance and high sensor properties. Herein, an Ecoflex@Juncus effusus/AgNW-based strain sensor with three-dimensional reticular structure was fabricated with a plant-based Juncus effusus (JE) fiber as the skeleton of the strain sensor, silver nanowire (AgNW) as the conductive component, and Ecoflex as the encapsulation layer. The AgNWs can easily infiltrate into the porous skeletons of JE and adsorb on the surface of the fibers, and the Ecoflex layer provides good protection for the JE and AgNW to ensure the outstanding flexibility of the final sensor. The fabricated Ecoflex@JE/AgNW sensor exhibits high sensitivity (3176.78), wide working range (0–135%), fast response to deformation, and good repeatability (over 5000 times). It provides a promising application in wearable sensors in the near future.

Graphical Abstract

Herein, an Ecoflex@Juncus effusus/AgNW-based strain sensor with three-dimensional reticular structure was fabricated with a plant-based Juncus effusus (JE) fiber as the skeleton of the strain sensor, silver nanowire (AgNW) as the conductive component, and Ecoflex as the encapsulation layer. The AgNWs with nanoscale diameter can easily infiltrate into the JE skeletons with a porous structure and large surface and adsorb on the surface of the fibers, and the Ecoflex layer provides good protection for the JE and AgNW to ensure the outstanding flexibility of the final sensor. The fabricated Ecoflex@JE/AgNW sensor exhibits high sensitivity (3176.78), wide working range (0–135%), fast response to deformation, and good repeatability (over 5000 times).
