A DIC Based Technique to Measure the Contraction of a Skeletal Muscle Engineered Tissue

Figure 3

Data analysis. Example of an X-MET spontaneous contraction measured through the micro-force transducer (a), with the corresponding FFT analysis (b), and through the digital image correlation technique (c), again with the corresponding FFT analysis (d). The values in (b) and (d) are and respectively. Images were acquired at 500 fps.
