Development of a standing wave based acoustic micropump for lab on chip applications

Develop an acoustic micropump to solve size scaling issue of micropump in lab on chip system for biological assay applications

Advances in microelectromechanical systems (MEMS) technologies, in recent decades, led to the fast development of microflow MEMS technologies with different functions. Among these, micropump plays an essential role which can be regarded as the heart of microfluidics. 
There are various types of micropumps in terms of different driving mechanisms. Many of the driving mechanisms have good pumping performance with larger scale which is not suitable for lab on chip integration. Among these driving mechanisms, acoustofluidics is more suitable for size scaling. The ultrasonic frequency is beyond tens of kHz and therefore can be particularly used in microfluidics and lab on chip systems.


The goal of this project is to use piezoelectric micromachined ultrasonic transducer (PMUT) as acoustic driver to generate a net fluid flow inside the chamber under acoustic standing wave field. This project is fully simulation based using COMSOL.
