摘要： Technologies are generally described for systems and methods effective to implement particle removal. In one example, a method for at least partially removing particles from a region is generally described. In some examples, the method includes applying an electric field to a material to produce an acoustic wave from the material. The material may have a periodic piezoelectric coefficient. The method may include applying the acoustic wave to the region to produce an agglomeration. The agglomeration may include at least two of the particles. The method may further include at least partially removing the agglomeration from the region.
