Biomechanical & Biomaterials Testing

Biomechanical scientists and engineers rely on reliable and accurate measurement data to model the complex movement and interaction of biological elements, such as; bones, implants, prostheses and cardiac surgery components. The measured mechanical properties from natural biological elements are replicated (& improved) for the development of artificial biomaterials, which are being used increasingly more in medicine for anatomical repair and substitution.

Digital Image Correlation (DIC) is a non-contact, full-field, optical measurement technology that can be used to measure surface (contour) shape, displacement and strain. A DIC system is versatile and can be used to measure components smaller than 10 x 10 mm using a stereoscopic microscope. Using a multi-camera setup, biomechanical testing applications that require 180° to 360° section measurements, such as; pelvises, jaws, spines, craniums (skulls) and Ventricular Assist Devices (VADs) can be also be accurately measured.
