“…Analysis of Table 3 and Table 4 highlights the substantial impact of microfiber diameter and deposited material concentration on the sensitivity of MKR. This study’s maximum normalized sensing efficiency (2.21 dB/°C/mm), as presented in Table 3 , surpassed the previous findings of our group (1.65 dB/°C/mm) [ 40 ]. Hence, choosing the suitable microfiber diameter and deposition material concentration can notably enhance the performance of MKR sensors, providing heightened sensitivity and accuracy in specific application scenarios.…”

We demonstrate an all-fiber, compact-structure, high-sensing-efficiency temperature sensor using a resonator structure sensor device of a runway type and MXene V2C. The high-quality functional material MXene V2C, synthesized by a simple two-step method, has excellent photothermal conversion performance. As-prepared MXene V2C is integrated into the runway section of a runway-type microfiber knot resonator based on the coupling mechanism between the surface near the field of the fiber and materials. When the temperature variation range is ~25–70 °C, the corresponding transmission light intensity variation is linear, and the maximum normalized sensing efficiency is 2.21 dB/°C/mm. Our work demonstrates that the runway-type structure ensures the compactness of the sensor device and enhances the interaction distance between the material and the microfiber, which provides additional integration strategies for functional material-based sensor devices.

MXenes have received worldwide attention across various scientific and technological fields since the first report of the synthesis of Ti3C2 nanostructures in 2011. The unique characteristics of MXenes, such as superior mechanical strength and flexibility, liquid-phase processability, tunable surface functionality, high electrical conductivity, and the ability to customize their properties, have led to the widespread development and exploration of their applications in energy storage, electronics, biomedicine, catalysis, and environmental technologies. The significant growth in publications related to MXenes over the past decade highlights the extensive research interest in this material. One area that has a great potential for improvement through the integration of MXenes is sensor design. Strain sensors, temperature sensors, pressure sensors, biosensors (both optical and electrochemical), gas sensors, and environmental pollution sensors targeted at volatile organic compounds (VOCs) could all gain numerous improvements from the inclusion of MXenes. This report delves into the current research landscape, exploring the advancements in MXene-based chemo-sensor technologies and examining potential future applications across diverse sensor types.

“…Recently, Wu et al presented for the first time the optical deposition of MXene vanadium carbide on a runway-type MKR surface, which, thanks to the effective coupling of this runway-type structure and the high photothermal effect of the 2D material, has a maximum sensing efficiency to temperature (0.33 dB °C−1 ) that is 2.7 times higher than that of the bare structure (0.09 dB °C−1 ). [99] Table 1 summarizes the performance of various temperature sensors based on MKR in recent years. In conclusion, MKRbased temperature sensors have been explored in an innovative way in terms of structure and principle, but are currently limited to laboratory conditions.…”

In recent years, compact micro‐/nanofiber sensors with fast response and high resolution have become a hot field in sensing and nanotechnology. In addition to the unique properties of microfibers such as strong evanescent field, low optical loss, and easy integration, microfiber knot resonators further improve the sensing capability due to their resonance properties. The potential high‐quality factor allows higher sensing sensitivity and resolution, which is very attractive for optical sensing at the micro‐/nano scale. More application potential can be effectively stimulated by improving the structure shape or principle or combining with functional sensitive materials. This paper first introduces the preparation process and spectral characteristics of conventional microfiber knots and then focuses on three new types of devices for enhancing the sensing performance, namely material‐coated, shape‐improved, and principle‐extended, and briefly analyzes their spectral properties. In addition, the research progress and applications of these sensors are summarized. Finally, the existing problems in this field are analyzed, and the directions for further development are discussed and prospected.
