Abstract
Thin film acoustic techniques have been used to fabricate surface acoustic wave (SAW) and film bulk acoustic wave (FBAR) applications, which have been used for sample preparation (sorting, mixing, pumping, nebulization and dispensing) as well as gas sensing and bio-sensing. This talk will focus on acoustic wave devices fabricated using piezoelectric thin films (mainly ZnO and AlN) for acoustic wave sensing and microfluidic applications. Engineering of piezoelectric films and their functional properties are analyzed. The fabrication process and characterization of integrated acoustic wave devices using sputtered thin films on various substrates were discussed, but more focusing on recent work of high performance devices achieved on polymer and metallic foils. The thin film based flexible SAW devices have the potential to be integrated with other microfluidic and sensing technology on a variety of substrates including CMOS integrated circuits to make novel lab-on-chip for bio-detection for wearable and flexible applications.
