This video demonstrates the use of a hand-held inkjet printer to apply high-quality speckle patterns for digital image correlation (DIC).
Hand-held printers enable fast, uniform patterning without gaps or clumps, making them well suited for soft tissues and other delicate specimens. The fine, fast-drying ink adheres to a wide range of biomaterials and supports accurate non-contact strain measurement.
The video shows the full workflow, including surface patterning, specimen mounting on a BioTester system, and image-based strain analysis using CellScale software.
