Tribochromism refers to a change in colour of a material caused by mechanical friction, similar to piezochromism, the change in colour of a material caused by pressure. It is a property of some materials and is often associated with thermochromism.[1] Tribochromism and piezochromism are often grouped together under the term mechanochromism.[2][3]
Tribochromatic materials may be used in sensors when friction has to be detected. These materials generally change colour under mechanical stress conditions; the colour gradually fades once the stress is removed.[4]
