Abstract
A time temperature monitoring system and method for use with a microchip or similar structure. A disclosed system includes: a substrate having an active region; a dopant source located proximate the active region; an activation system for activating a diffusion of the dopant source into the active region; and a set of spatially distributed electrodes embedded in the active region of the substrate, wherein the electrodes are configured to detect the diffusion in the active region at varying distances from the dopant source to provide time temperature information.
