Towards a universal flow sensor for microfluidics


With the development of microfluidics and its applications in life sciences, the need for disposable sensors capable of measuring flow rates over wide ranges and without prior calibration steps has increased. However, commercially available flowmeters or those reported in the literature only partially meet these specifications. The aim of this Ph.D. work has been to address these needs thanks to an innovative measuring principle: a microscopic wheel driven by the liquid motion.

What will be covered?

We will first present the manufacturing processes implemented, based on the photopolymerization of a photosensitive liquid. As we predicted a linear response of the sensor, independent of the liquid viscosity, and varying according to the wheel radius, we will compare the results obtained experimentally to the theoretical model. Then, we will discuss the measured wheel movement fluctuations, phenomena that were not initially predicted. Finally, based on a new model that describes the deformation of a microfluidic channel, we will discuss the influence of flow asymmetries and the wheel confinement on its rotation.

Why you should attend:

  • Learn more about current microfluidics flow sensor technologies
  • Discover a new approach to measure the flow rate at a microfluidic scale
