Integration of GaAs-based Lateral Field Excitation (LFE) Sensor with PDMS Microfluidic Channel : Simulation and Experimental Validation

Résumé

The losses in acoustic signals strength is one of the biggest hurdles in the integration process of acoustic waves-based sensor with PDMS microfluidic channel, due to the viscoelasticity of PDMS. Here we design, simulate and experimentally validate two different structures of GaAs-PDMS integrated microfluidic devices, where we found that the impact of viscous damping from PDMS can be reduced by using a thicker GaAs frame around the suspended active plate area that confines the acoustic energy in the transducer and acts as a microfluidic channel.
