Abstract
Articles of manufacture, including an apparatus for omnidirectional spiral surface acoustic wave generation, are provided. An acoustic wave device that generates a plurality of acoustic wave includes a piezoelectric material to convert electric energy into the plurality of acoustic waves. The acoustic wave device also includes a transducer. The transducer includes a plurality of fingers arranged in a spiral formation. The plurality of acoustic waves induce acoustic streaming along the piezoelectric material in multiple directions to isolate a fluid component within a fluid located on the acoustic wave device.
