Metamaterials exhibit functional properties that originate from their 3D architecture rather than their chemistry. In this project, we aim to explore the design and fabrication of acoustic metamaterials with exceptional sound-absorbing properties originated from a microstructure consisting of controlled building blocks. With a recently-developed technology for 3-dimensional printing of foams (not yet published), the pore size, interconnectivity, and the outer 3D-shape can be locally and independently controlled. Without any optimization and despite the random alignment of the unit cells, these foams already exhibit strong acoustic absorption properties at a highly relevant spectrum of ~400 Hz to 6 kHz. In view of our preliminary results, the goals of this project are:
Goal: Tunable soft acoustic metamaterials design and fabrication.
How: By combining your skills in acoustics with our technologies for 3D printing of modular materials including foams.
Why: The route of soft processing techniques opens up many ways of designing and fabricating new materials. Foams are extremely promising, as their hierarchical structure can be exploited to reach exceptional acoustic performances in very wide wavelength spectrum while keeping small size and high scalability.
Where: You will work in the Fluid Mechanics for Functional Materials group in collaboration with the Multi Scale Mechanics group, both at Faculty of Engineering Technology at the University of Twente. The position is part of an interdisciplinary team of young faculty that closely collaborates on design and scalable fabrication of Soft Metamaterials.
