Strain gauges and strain gauge transducers are important tools in the field of material resistance research to measure stresses strains solids. These methods devices have a wide range applications, from construction mechanical engineering, where properties materials need be monitored optimized. The use nanomaterials allows for more sensitive compact sensors. Nanotechnology makes it possible create with improved electrical properties. At same time, unique that make them ideal gauges. This paper considers different types composites based on polymer matrices additives dispersed nanomaterials, which designed tasks. Thermoplastics elastomers can used as matrices. Dispersed fillers MXene such carbon nanotubes, graphene, metals, etc. Despite obvious advantages conducting polymers modified structures, there problems creating effective ability operate under large deformations an sensitivity accuracy measurements range. article also provides brief information technical evolution gauges, wire foil nanocomposites. A modern classification is provided. disadvantages existing shown. review contains commercial mechanisms conductivity formation described detail. areas application nanocomposite specified purpose this study determine prospects various aimed at readers.

Sensitive Mechanism and Instability Modeling Methods of Flexible Sensing Films Based on 2D Materials

Crystals, Journal Year: 2025, Volume and Issue: 15(2), P. 130 - 130

This paper examines sensing mechanisms and stability issues of flexible sensors used in morphing wing applications. A key challenge is the lack theoretical frameworks that accurately predict sensor behavior during complex deformation. Current models struggle to fully capture relationships between mechanical strain, electrical response, material properties. We first analyze microscopic macroscopic characteristics 2D material-based sensitive films, developing strain-sensitive based on crack effects pressure-sensitive slip effects. Through power spectrum analysis, we establish a quantitative model linking cracks Using this model, study factors affecting propose description using dual-layer multi-channel sensors. After simulation validation, our successfully guides structural design offering clear approach improve stability.
