Piezochromism materials:research and application advancements
In the critical stages of precise assembly of device components,quality monitoring during product manufacturing,and performance evaluation,the detection of interface pressure is essential for optimizing production processes,strengthening quality control,and enhancing product stability.Although pressure sensors based on electrical signals exhibit significant advantages in terms of response rate,sensitivity,and pressure response range,they face limitations in interface pressure imaging,including high costs,stringent testing conditions,and the complexity of coordinating multiple devices.In recent years,piezochromic materials have garnered extensive research interest in the field of interface pressure detection due to their high-pressure imaging resolution,low cost,and ease of large-scale preparation.Currently,piezochromic materials have achieved precise visualization of pressure distribution,with imaging resolution reaching the nanometer scale.However,challenges remain in regulating pressure sensing accuracy,sensitivity,and response range.Based on this context,this paper reviews the development of piezochromic materials in recent years,focusing on their piezochromic principles,structure-property relationships,and performance characteristics.Additionally,the paper explores future development prospects and potential trends in piezochromic materials.
