Abstract :
Recently published works have demonstrated the interest of surface acoustic waves (SAW) for guiding and positioning small liquid droplet atop a flat surface. The application fields of such device mainly concern biochemical tools for well-controlled interaction of given bodies and small volume experimentation. In the proposed paper, the fabrication of a SAW-based X-Y stage on LiNbO3 for positioning small liquid droplet is described. An actuation strategy to accurately control the motion and detect the position of the droplet have been developed.
