Abstract

This paper presents integrated microfluidiclab-on-a-chip technology combining surface acoustic wave(SAW) and electro-wetting on dielectric(EWOD). This combination has been designed to provide enhanced microfluidic functionality and the integrated devices have been fabricated using a single mask lithographic process. The integrated technology uses EWOD to guide and precisely position microdroplets which can then be actuated by SAWdevices for particle concentration, acoustic streaming, mixing and ejection, as well as for sensing using a shear-horizontal waveSAWdevice. A SAW induced force has also been employed to enhance the EWODdroplet splitting function.
