The rational design and applications of MXene-based materials have yielded remarkable progress in flexible sensors, including wearable devices, soft robots, and smart medical equipment. The emerging MXene and substrate materials can be precisely engineered to improve the mechanical properties and sensing sensitivity of the sensors, opening up a wider range of application possibilities for MXene-based sensors. Therefore, a systematic and comprehensive review summarizing the progress of MXene-based sensor research based on these backgrounds is necessary. First, we discuss the basic structure of MXene materials and introduce the flexible substrate materials for MXene-based flexible sensors in detail. Then, we also discuss the different preparation methods of MXene-based sensors, describe the classifications, and highlight the applications of MXene-based flexible sensors in various scenarios. Finally, we identify the challenges that need to be overcome to accelerate the development of MXene-based materials in flexible sensing. This review provides a comprehensive and systematic insight into MXene-based flexible sensors and it is expected that this review will contribute to the development of higher performance MXene-based flexible sensors.

NiCo2O4, as a low‐cost and high‐performance binary transition metal oxide material, has been widely used in the fabrication of supercapacitor electrodes. However, the low energy density of binary metal oxides limits their large‐scale practical applications in supercapacitors, so it is highly desirable to design the structure of the NiCo2O4‐based supercapacitor. Therefore, in this paper, NiCo2O4 is compounded with polyaniline (PANI) to improve its electrochemical performance by exploiting the synergistic effect. The NiCo2O4@PANI composite electrode exhibits a specific capacitance of 561.2 F/g at 10 mV/s. In this study, asymmetric supercapacitors are assembled with NiCo2O4@PANI as the positive electrode and MXene as the negative electrode. The NiCo2O4@PANI‐CC//MXene‐CC supercapacitor has a specific capacitance of 31.95 F/g at a scan rate of 10 mV/s and a good cycle retention capacity of 86.2% after 3000 cycles. The excellent electrochemical performances are attributed to the dynamic equilibrium and fast redox kinetics of the two electrodes.
