Movie S1.
Activation of one sarcomere within a myofibril. A myofibril held by two precalibrated microneedles. Activation of one sarcomere using a microflow from the microfluidic perfusion (center of the video) causes displacement of the microneedles. Movie was accelerated by 5×.
Microfluidic perfusion shows intersarcomere dynamics within single skeletal muscle myofibrils
