Abstract
The disclosure relates to materials and articles that provide an irreversible history of compression forces and torques experienced by the materials and articles. The disclosure relates more particularly to an multiple impact level detection assembly as well as related articles and methods. The multiple impact level detection assembly provides distinct impact patterns depending on the impact force and direction (for torqueing motions) received by the detection assembly. The detection assembly can be incorporated into a variety of articles and used in a variety of settings, for example to monitor personal safety in a protective garment such as a helmet. The detection assembly incorporates an impact detection medium (e.g., a plurality of microcapsules with an indicator therein), which can serve as an irreversible means for detecting impact on the assembly via a relief substrate incorporated into the assembly.
