Tuning flow asymmetry with bio-inspired soft leaflets
Martin Brandenbourger, Adrien Dangremont, Rudolf Sprik +1
In Nature, liquids often circulate in channels textured with leaflets, cilia or porous walls that deform with the flow. These soft structures are optimized to passively control flo…
Observation of non-Hermitian topology and its bulk-edge correspondence in an active mechanical metamaterial
Ananya Ghatak, Martin Brandenbourger, Jasper van Wezel +1
Topological edge modes are excitations that are localized at the materials' edges and yet are characterized by a topological invariant defined in the bulk. Such bulk-edge correspon…
Non-reciprocal robotic metamaterials
Martin Brandenbourger, Xander Locsin, Edan Lerner +1
Non-reciprocal transmission of motion is potentially highly beneficial to a wide range of applications, ranging from wave guiding, to shock and vibration damping and energy harvest…
Physics of a toy geyser
Martin Brandenbourger, Stéphane Dorbolo, Baptiste Darbois Texier
A geyser can be reproduced by a toy experiment composed of a water pool located above a water reservoir, the two being connected by a long and narrow tube. When the bottom reservoi…
Electrically charged droplet: Influence of the generator configuration and the nature of the liquid
Martin Brandenbourger, Stephane Dorbolo
We studied how to charge droplets by induction and how to maximize this charge. In order to aim this objective, we developed an innovative device that avoids non-linear effects and…
