Kiel Nano, Surface and Interface Science (KiNSIS)

Acoustic wave lab-on-chip is now flexible, bendable and potentially wearable! (Prof. Richard Fu, Newcastle)

28.05.2018 von 17:15 bis 18:00

Institute Ostufer, Geb. D, "Aquarium", Kaiserstr. 2, 24143 Kiel

Abstract:

 

Thin film acoustic wave devices especially surface acoustic waves (SAW) have been used for sample preparation (sorting, separating, mixing, nebulization and dispensing) as well as bio-sensing. This talk will focus on our recent work of flexible and wearable thin film acoustic wave lab-on-chip (mainly using ZnO and AlN films on flexible substrates) for acoustic wave based microfluidic applications. We report theoretical and experimental studies of the evolution, hybridization and decoupling of wave modes in the flexible acoustic wave devices, as well as their vibration patterns. thus providing a guide for different microfluidic applications. Thin film based flexible SAW devices have the potential to be integrated with other microfluidic and sensing technology on flexible substrates including CMOS integrated circuits to make novel lab-on-chip for bio-detection for wearable and flexible applications. SAW devices on commercial polymer and aluminum foils have been fabricated and various microfluidic functions, such as mixing, pumping, jetting have been demonstrated with bent and deformed acoustic wave devices.
