Abstract
A barcode includes sensors or actuators in selected modules whereby its code changes to indicate exposure to, or change in, one or more properties of interest. Prior to exposure, the barcode displays a first code. After exposure, the barcode displays a different code. The displayed code conveys qualitative or quantitative information about one or more chosen properties of interest. This dynamic barcode can be configured as a standalone device or as a label that can be affixed to an object. Data coded by the dynamic barcode is machine-readable or visible to the naked eye, and can be autonomously conveyed to a database to facilitate analysis or prognostics.
