Standing surface acoustic wave (SSAW) technology combined with microtechnology opens up new areas for the development of advanced microparticle and cell separating microfluidic system. A novel SSAW sensor made of the orthotropic piezoelectric composite material (OPCM) is proposed and described. A SSAW field with target wavelength can be generated by this technology and with this new sensor. The wavelength of SSAW generated by this sensor can vary the range from several to a few hundred micrometers. The acoustic radiation force (ARF) generated by the SSAW field can be used to manipulate different dimensional particles.

Two numerical methods based on the Finite Element Method are presented for calculating the secondary acoustic radiation force between interacting spherical particles. The first model only considers the acoustic waves scattering off a single particle, while the second model includes re-scattering effects between the two interacting spheres. The 2D axisymmetric simplified model combines the Gor’kov potential approach with acoustic simulations to find the interacting forces between two small compressible spheres in an inviscid fluid. The second model is based on 3D simulations of the acoustic field and uses the tensor integral method for direct calculation of the force. The results obtained by both models are compared with analytical equations, showing good agreement between them. The 2D and 3D models take, respectively, seconds and tens of seconds to achieve a convergence error of less than 1%. In comparison with previous models, the numerical methods presented herein can be easily implemented in commercial Finite Element software packages, where surface integrals are available, making it a suitable tool for investigating interparticle forces in acoustic manipulation devices.
