Full-field strain measurements on medical devices using digital image correlation: Considerations and practical examples.

ABSTRACT: Access to direct stress or strain measurements on implantable medical devices could transform device design, durability assessment, and computational model development and validation activities. However, examples of acquiring such measurements are lacking. Here, we consider the use of optical digital image correlation (DIC) for characterizing full-field strains on medical devices and medical device surrogate specimens. Several common and unique speckle pattern application approaches are investigated including aerosol painting, application of transfer or decal papers, low- and high-pressure airbrushing using traditional and ultra-low reflectance paints, deposition of monodisperse graphite powder, and custom microstamping. Among the methods considered, comparative speckling studies show high
