Highlights Convincing candidates of flexible (stretchable/compressible) electromagnetic interference shielding nanocomposites are discussed in detail from the views fabrication, mechanical elasticity and performance. Detailed summary relationship between deformation materials The future directions challenges developing (particularly elastic) highlighted. Abstract With extensive use electronic communication technology integrated circuit systems wearable devices, (EMI) has increased dramatically. shortcomings conventional rigid EMI include high brittleness, poor comfort, unsuitability for conforming deformable applications. Hitherto, have attracted enormous interest due to their excellent deformability. However, current present low stability resilience, relatively performance, limited multifunctionality. Herein, advances low-dimensional nanomaterials-based elastomers outlined a selection most remarkable examples is discussed. And corresponding modification strategies deformability performance summarized. Finally, expectations this quickly increasing sector discussed, as well challenges.

Abstract Flexible wearable strain sensors have received extensive attention in human–computer interaction, soft robotics, and human health monitoring. Despite significant efforts developing stretchable electronic materials structures, flexible with stable interfaces low hysteresis remains a challenge. Herein, Ti 3 C 2 T x MXene/AgNWs/liquid metal (MAL sensor) self‐healing function are developed by exploiting the strong interactions between MXene/AgNWs/LM disulfide hydrogen bonds inside poly(dimethylsiloxane) elastomers. AgNWs lap MXene sheets, LM acts as bridge to increase AgNWs, thereby improving interface interaction them reducing hysteresis. The MAL sensor can simultaneously achieve high sensitivity (gauge factor for up 3.22), linearity ( R = 0.98157), wide range of detection (e.g., 1%–300%), fast response time (145 ms), excellent repeatability, stability.In addition, before after is combined small fish an electrothermally driven robot, respectively, allowing real‐time monitoring swinging tail crawling robot resistance changes.
