Abstract
A stress history recording system for recording a stress history, which includes a light emitting section including a stress-stimulated luminescent material that emits light in response to a mechanical external force, and a recording section for recording a history of a photoreaction generated due to light emission from the light emitting section. This achieves a technology for recording a stress history by using the stress-stimulated luminescent material.
