Phononic-Fluidic Systems

The combination of so-called phononic crystals with microfluidic systems is a novel approach to develop a platform exploiting physical properties for the (bio)chemical analysis of liquids and mixtures. Taking advantage of additive fabrication we design and build three-dimensional lattices to control acoustic wave propagation. These structures will then be integrated around and within microfluidic cavities and channels.

Project description

For this project we combine fundamental research in the field of phoNonic crystals, the acoustic equivalent of phoTonic crystals from optics, with the rapidly growing possibilities of additive manufacturing. We design, simulate and print 3D structures with physical properties not found in corresponding 1D and 2D crystals. The main unique feature of phononic crystals is the existence of complete band gaps, frequency regions where acoustic wave propagation is not possible.

Integration of these structures with microfluidic systems can also be simplified with the use of additive fabrication. Designing a fluidic element such as a cavity or channel into the crystal lattice allows defect engineering comparable to introducing defect atoms into a semiconductor lattice. With proper design, a fluid inside such a defect can give rise to a signal peak inside a phononic band gap, giving direct access to its volumetric physical properties.

The goal of this research is the discovery of suitable structures, materials and combinations with fluidic elements that exhibit the necessary behavior. Here and in follow-up projects we aim to develop a novel class of phononic-fluidic systems as, e.g., sensing platform for the analysis of different liquids and mixtures, but also for the detection and manipulation of particles and cells inside such fluids.

The procject was funded from 15.01.2019 to 31.10.2022 by the DFG  within an ANR-DFG French-German Collaboration for Joint Projects in Natural, Life and Engineering Sciences under the title of „Tubular Bell“.

Partners: Otto-von-Guericke-University Magdeburg, University Pierre et Marie Curie Paris, University Lille.
