Abstract
A method and apparatus for manipulating polarizable dielectric particles. The method includes positioning a liquid containing the particles above a surface of a piezoelectric material (). The method also includes inducing a shear-horizontal surface acoustic wave in the piezoelectric material (), thereby to form a time-varying non-uniform evanescent electric field extending into the liquid. The method further includes using the time-varying non-uniform evanescent electric field to apply a force to at least some of the particles () by dielectrophoresis.
