Particle manipulation by adhere method as travelling surface acoustic wave

Surface acoustic wave (SAW) is waves that propagate on the surface of the substrate. The propagating wave generated by applying the alternating voltage across electrodes on piezoelectric substates. By the propagating waves, it can be used for the separation of particles. There are two important p...
