Abstract :
A new concept of SAW powered lab on chip able to actuate and to perform accurate sensing is presented. Using IdT/ZnO/IdT/Quartz structure, it is possible to obtain simultaneously Rayleigh and Love waves. The first wave will be used to mix or heat whereas the second one will be use to sense. In order to determine the optimal characteristics, a theoretical approach has been developed. A comparison between our former classical microfluidic device and the new structure is presented. First results are explained.
