Abstract. Since the field of microfluidics is vastly improving and developing, and piezoelectric actuators offer good control on a micrometer scale, this work was created as a combination of the two. A microfluidic chip with an embedded piezoelectric actuator was designed and constructed using polydimethylsiloxane as the main material. The chip was experimented on by varying both mechanical and electrical properties. Performance dependencies of volumetric flow rate and input waveform were described and analyzed. Moreover, beneficial phenomena were discovered and analyzed using high‑speed microscopy and digital image analysis. A situation where control of microfluidic flow direction could potentially be available was achieved. Other promising results showed new potential applications for piezoelectric actuation in microfluidic systems.

Keywords: piezoelectric actuation, microfluidics, cell sorting.
