Résumé

In this paper, we have studied the temperature uniformity of microdroplet heated by Rayleigh surface acoustic wave for discrete microfluidic applications such as biological reactions. A longitudinal wave is radiated into the liquid placed on the wave path and induces the well known surface acoustic wave streaming. To precisely ascertain the temperature uniformity, we have used a non-contact method based on infraed thermography so as to not interfer with the biological reaction. We then have tested the temperature uniformity as a function of three parameters: the microdroplet volume, the Rayleigh surface acoustic wave frequency and the injected power. Based on these results, we propose a new device structure to develop a futur lab on chip based temperature reaction.
