Biomedical engineering is an interdisciplinary scientific field dedicated to improving human health and medical care. From an engineering perspective, it involves the interaction of biomaterials, mechanobiology, and biomanufacturing processes with target biological systems to achieve various medical therapeutic goals. Digital Image Correlation (DIC)—a non-contact, precise, efficient, and non-destructive full-field strain measurement method—can be used to measure the mechanical properties and behaviors across the entire field of view in complex applications involving mechanobiology, biomaterials, bioprinting, and manufacturing.
Biomaterials often feature complex geometries, making it extremely difficult to measure soft tissues or intricate bone structures under load using contact sensors—particularly regarding the maintenance of contact and attachment between the sensor and the specimen throughout the experiment. In some instances, contact sensors may even alter the material's properties.
DIC technology offers a user-friendly, non-contact measurement solution to these challenges. Furthermore, it enables high-precision, full-field measurement of an object's profile, displacement, and strain. By providing thousands of measurement points, DIC helps researchers understand the complex interplay of physical characteristics in specimens under load and yields high-quality experimental data for validating and optimizing computational models.
