Cutting-edge technologies of stretchable, skin-mountable, and wearable electronics have attracted tremendous attention recently due to their very wide applications and promising performances. One direction of particular interest is to investigate novel properties in stretchable electronics by exploring multifunctional materials. Here, we report an integrated strain sensing system that is highly stretchable, rehealable, fully recyclable, and reconfigurable. This system consists of dynamic covalent thermoset polyimine as the moldable substrate and encapsulation, eutectic liquid metal alloy as the strain sensing unit and interconnects, and off-the-shelf chip components for measuring and magnifying functions. The device can be attached on different parts of the human body for accurately monitoring joint motion and respiration. Such a strain sensing system provides a reliable, economical, and ecofriendly solution to wearable technologies, with wide applications in health care, prosthetics, robotics, and biomedical devices.

Electronic skin is driving the next generation of cutting-edge wearable electronic products due to its good wearability and high accuracy of information acquisition. However, it remains a challenge to fulfill the requirements on detecting full-range human activities with existing flexible strain sensors. Herein, highly stretchable, sensitive, and multifunctional flexible strain sensors based on MXene- (Ti3C2Tx-) composited poly(vinyl alcohol)/polyvinyl pyrrolidone double-network hydrogels were prepared. The uniformly distributed hydrophilic MXene nanosheets formed a three-dimensional conductive network throughout the hydrogel, endowing the flexible sensor with high sensitivity. The strong interaction between the double-network hydrogel matrix and MXene greatly improved the mechanical properties of the hydrogels. The resulting nanocomposited hydrogels featured great tensile performance (2400%), toughness, and resilience. Particularly, the as-prepared flexible pressure sensor revealed ultrahigh sensitivity (10.75 kPa-1) with a wide response range (0-61.5 kPa), fast response (33.5 ms), and low limit of detection (0.87 Pa). Moreover, the hydrogel-based flexible sensors, with high sensitivity and durability, could be employed to monitor full-range human motions and assembled into some aligned devices for subtle pressure detection, providing enormous potential in facial expression and phonation recognition, handwriting verification, healthy diagnosis, and wearable electronics.

In textile and wearable electronics, the demand for a stretchable, durable, and easily manufacturable electrode is ever increasing. This paper describes the development of a highly stretchable and durable textile electrode fabricated by simple stencil and screen printing methods. It specifically investigated the effects of an interface layer as a planarization layer between the conductive electrode and the textile on the durability of the textile electrode. A stretchable conductive paste was synthesized by mixing Ag flake powder in polyester. The conductive electrode was encapsulated with Ecoflex material. The stretchability and durability of the textile electrodes were evaluated via stretching, bending, Massachusetts Institute of Technology (MIT) folding, twisting, and dynamic endurance tests. The stretching and MIT folding tests indicated that the interface layer significantly enhanced the durability of the textile electrode. A highly stretchable and flexible textile electrode exhibited a low sheet resistance of 0.05 Ω/square, excellent stretchability of 70%, and a critical bending radius of 1.5 mm. The textile electrodes also withstood dynamic stretching and bending endurance tests of 10,000 cycles. The illumination of a light-emitting diode with the conductive electrode was also stable under 70% tensile strain and in water. The potential application of the textile electrode as a strain sensor was demonstrated by applying it to a glove to detect finger motion. The strain sensors responded well to the finger motion, with considerable stability and repeatability.
