Spiral-based phononic plates: From wave beaming to topological insulators
André Foehr, Osama R. Bilal, Sebastian D. Huber +1
Phononic crystals and metamaterials take advantage of pre-designed geometrical structures to sculpt elastic waves, controlling their dispersion using different mechanisms. These me…
Harnessing bistability for directional propulsion of untethered, soft robots
Tian Chen, Osama R. Bilal, Kristina Shea +1
In most macro-scale robotics systems , propulsion and controls are enabled through a physical tether or complex on-board electronics and batteries. A tether simplifies the design p…
Observation of a phononic quadrupole topological insulator
Marc Serra-Garcia, Valerio Peri, Roman Süsstrunk +4
The modern theory of charge polarization in solids is based on a generalization of Berry's phase. Its possible quantization lies at the heart of our understanding of all systems wi…
Intrinsically polar elastic metamaterials
Osama R. Bilal, Roman Süsstrunk, Chiara Daraio +1
The ability to design and fabricate materials with tailored mechanical properties, combined with immunity to damage, is a frontier of materials engineering. For example, materials…
