Acoustic mixer using low frequency vibration for biological andchemical applications

Résumé

Liquid mixing at micro-scale is considered a challenge which is even tougher to overcome in the caseof discrete microfluidic. Many researchers have developed strategies and tried to be pioneer in mixingsolutions for lab on chip. In this paper, we present a parallel microdroplet mixer based on acoustic fieldgeneration using a low frequency vibration (up to few hundreds of kilohertz). This device can be usedfor lab on chip applications, since the liquid characteristics are not disturbed by the plugged energy andinvolve relatively simple microfabrication techniques. We designed, fabricated, evaluated, presentedexperiments showing the microdroplet active mixing, and investigated the thermal effect of the createdacoustic energy.
