“…Figure 7a shows the electromechanical behavior of a highly stretchable strain sensor (stretchability %500%) based on a polymer composite consisting of graphene, poly(acrylic acid) (PAA), and amorphous calcium carbonate (ACC). [141] In this composite, graphene nanosheets and calcium ions (Ca 2þ ) formed a double crosslinkers with low stiffness that could play a key role in achieving high stretchability. Xu et al reported an ultrastretchable capacitive-type strain sensor based on ionic hydrogels and conductive Ag NF nanocomposites as a dielectric layer and stretchable electrodes, respectively.…”

Recent advances in the design and implementation of wearable resistive, capacitive, and optical strain sensors are summarized herein. Wearable and stretchable strain sensors have received extensive research interest due to their applications in personalized healthcare, human motion detection, human–machine interfaces, soft robotics, and beyond. The disconnection of overlapped nanomaterials, reversible opening/closing of microcracks in sensing films, and alteration of the tunneling resistance have been successfully adopted to develop high‐performance resistive‐type sensors. On the other hand, the sensing behavior of capacitive‐type and optical strain sensors is largely governed by their geometrical changes under stretching/releasing cycles. The sensor design parameters, including stretchability, sensitivity, linearity, hysteresis, and dynamic durability, are comprehensively discussed. Finally, the promising applications of wearable strain sensors are highlighted in detail. Although considerable progress has been made so far, wearable strain sensors are still in their prototype stage, and several challenges in the manufacturing of integrated and multifunctional strain sensors should be yet tackled.

“…Therefore, improving the durability of the FGS to retain a stable sensing performance is worthy to be further studied. [92,93] In general, FGS usually have properties of good stretchability, high sensitivity, and low linearity. At the same time, hysteresis, response and recovery time, and overshoot behavior are inevitable due to the viscoelasticity of the fiber forming polymers that used as FGS substrate, so its influence on the sensing accuracy can only be reduced or corrected as much as possible.…”

With the development of wearable electronic devices, electronic-textiles have attracted more and more attentions due to its widely applications in human movement monitoring, health and physical indicators monitoring (e.g. heartbeat, pulse, body temperature, limb movements, and vocalization). As a vital part of electronic textiles, graphene strain sensors that based on fiber assemblies (FGS) is of concern to the researchers due to its well integration of graphene with fibers assemblies, which will inevitably promote the rapid development and widespread applications of next-generation wearable electronic devices. Fiber assemblies exhibit outstanding ability of structural retention and fatigue resistance during wearing and washing, which can provide a large-area affiliated carrier and widespread service platform for the design and application of electronic-textiles. And the graphene endows electronic-textiles with good electrical and mechanical properties. Herein, the previous researches on fabrication, sensing mechanism, sensing performance indexes, and application field of FGS are systematically summarized. Furthermore, the potential difficulties and future development prospect of FGS are summarized and discussed. It is expected that this review is not only a summary of what has been achieved, but also provide a guideline for future development.

“…By taking advantage of a polymer's nature, all kinds of excellent structures with the uniform size of the 0D micro-ball can be synthesized. Based on electrostatic interactions, RGO would cover the polymer balls to produce polymer ball @RGO nanoparticles [128][129][130][131]. Due to the bending of graphene sheets by the van der Waals attractive force, the PMMA ball @ RGO-based tactile sensor, at pressures < 1 torr, showed an increased resistance value [131].…”
