Gallium‐based liquid metal (LM) is widely used in flexible electronics, optics, and green synthesis due to its excellent conductivity, flexibility, and self‐healing capabilities. However, LM's inherent fluidity and high surface tension greatly limit their practical applications. Therefore, there is a strong demand for developing LM composites that are easy to control and exhibit outstanding performance when used flexibly. In this work, the LM hydrothermal rheological modification method is proposed to synthesize Ga‐coated carbon microparticles, and the highly miscible rheological modification of LM is realized by mixing LM and Ga‐coated carbon microparticles. Including carbon microparticles in the LM improves the mechanical strength of the composite, thereby overcoming the limitation of the LM that has a low mechanical strength. By controlling the volume fraction of carbon microparticles in LM, electrical conductivity is increased by 30% and thermal conductivity by more than 2.0 times that of pure LM. In addition, the fundamental interfacial wetting behavior is demonstrated at the interface of LM and Ga2O3, and the rheological modification mechanism of LM is explained by carbon particles. This work presents a novel method for preparing high‐performance polymer materials and discusses their broad potential applications in thermal interface materials, wireless energy transfer, and flexible electronics.

Strain measurement is crucial for the safety and stability of engineering activities. With the increasing demand for sensors and large strain measurement in engineering monitoring, the study on the large strain measurement is deepening. However, the conventional strain sensors based on rigid conductive materials have limited flexibility and low stretchability, and the research of large strain and flexible sensors in engineering still lacks. In this work, a highly stretchable and sensitive flexible strain sensor based on liquid metal‐Nickle microparticles (LMN) composite is developed to detect large strain. The LMN composite, featuring uniformly dispersed Nickle microparticles within the liquid metal matrix, is deposited onto the elastomer Ecoflex base material.The LMN composite based‐sensor exhibits high sensitivity (GF = 16.14644 at strain of 200%), large stretchability (up to 200%) and low hysteresis. The theoretical relationship between the relative resistance changes and strain is derived, and the theoretical derivation is compared with experimental data to verify the accuracy of theoretical derivation. Additionally, the LMN composite based‐sensors can be used to detect pressure and bending signals in engineering. This work highlights the potential of LMN composite in broad applications and can facilitate the application of flexible sensing devices in engineering. [ABSTRACT FROM AUTHOR]
