A PDMS-based broadband acoustic impedance matched material
Splet10. feb. 2024 · Polydimethylsiloxane (PDMS) is widely used as a channel material in microfluidic applications. Due to its highly elastomeric characteristics, PDMS absorbs the acoustic energy of the surface acoustic waves (SAWs) generated by the interdigital transducers (IDTs). Insertion loss is one of the indicators that present the degree of … Splet13. jul. 2016 · The effect of a physical PDMS boundary over the fluid domain is minimal, resulting in a small amount of reflection due to the fractional acoustic impedance difference between water and PDMS and thus a degree of acoustic patterning in the z direction, although the magnitude of this effect is secondary to that of primary patterning. daytona beach cost of living
