Abstract :
We present a simulation of acoustic tweezers that will improve our understanding of standing surface acoustic wave (SSAW) generation in microfluidic chips made of soft polymers such as polydimethysiloxane (PDMS). This simulation aims at providing a tool to improve acoustofluidic chip design. In this paper, we describe a finite element method (FEM) modeling approach of a complete acoustofluidic chip including two interdigitated transducers (IDTs) and a PDMS microchannel in between. The acoustic radiation force exerted on particles in the microchannel is computed for different phase shifts between the two input signals.
