1. A method for harmonic acoustic manipulation of particles, the method comprising:
introducing particles into a fluid positioned over a first surface of a piezoelectric substrate;
generating a first harmonic signal comprising a plurality of harmonic components; and
applying the first harmonic signal to a first harmonic acoustic transducer, wherein the first harmonic acoustic transducer is coupled to the first surface of the piezoelectric substrate and spaced apart from the fluid.
