This video demonstrates real-time image-based strain control in CellScale mechanical testing systems. Instead of relying on actuator displacement or force feedback, test protocols are driven by measured specimen strain within a defined region of interest.
By tracking deformation directly on the specimen surface, this approach reduces variability caused by grip slip and localized deformation outside the gauge region. The result is more consistent strain control, improved repeatability between samples, and higher-quality data for constitutive modeling.
