In the two videos below we can see our piezo driver MMP - S1 2ax being used at McGill University (Dep. of Physiology) by Felipe (in the picture), in a real experiment. 


The video shows a myofibril sample in caught in between 2 glass needles. the experiment is filmed under 60X magnification on an inverted microscope. The striations on the sample are on the order of a couple of microns. This can give an idea of the precision of the motion. Only the upper needle is connected to the piezo actuator. The rest of the motion is due to environmental vibrations. 

On the computer screen we see the traces of 2 glass microneedles captured by a linear array CCD, through an inverted microscope at 100X. The structure on the left is connected to the piezo. We make steps of one microns each.
