Beschreibung
Zusammenfassung:	A color switchable stress/fracture sensor in combination with a structure. The combination apparatus includes a structure requiring stress and/or fracture detection, and at least one elasto-mechanoluminescent material at least partially dispersed in and/or on the structure and/or in a coating on the structure. The combination apparatus further includes at least one fracto-mechanoluminescent material at least partially dispersed in and/or on the structure and/or in a coating on the structure, and at least one fiber optic cable positioned to receive and transmit sufficient light emitted from the elasto-mechanoluminescent material due to stress applied to the elasto-mechanoluminescent material and to receive and transmit sufficient light emitted from the fracto-mechanoluminescent material due to fracture of the fracto-mechanoluminescent material.
