The disclosure relates to an irreversible dosimetric shock-detection substrate as well as related articles and methods. The shock-detection substrate incorporates a plurality of microcapsules serving as an irreversible means for detecting impact on the substrate. A shock above a characteristic threshold level experienced by the substrate induces an irreversible detectable change associated with the microcapsules upon shock-induced rupture. The irreversible detectable change provides a tamper-proof and non-electronic means for detecting a shock or impact. The shock-detection substrates can be incorporated into a variety of articles and used in a variety of settings, for example to monitor personal safety, to monitor article integrity, to monitor the end of the useful life of the shock-detection substrate itself, or in any other setting where it is desirable to irreversibly detect and/or localize a shock event.
