Active particle in a very thin interfacial droplet
Airi N. Kato, Kaili Xie, Benjamin Gorin +2
A single light-driven Janus particle confined in a very thin oil droplet at an air--water interface displays intriguing dynamics. While laser activation induces rapid horizontal mo…

Controlled Locomotion of a Minimal Soft Structure by Stick-Slip Nonlinearity
Thomas Barois, A. Boucherie, L. Tadrist +1
We present a locomotion mechanism that uses the stick-slip transition of a soft passive structure with an internal mechanical resonance. The structure is harmonically driven by a g…

Impacts of poroelastic spheres
Gorin Benjamin, Ribe Neil, Bonn Daniel +1
We study experimentally the impact on rigid surfaces of different soft porous solids saturated with liquid: hydrogel balls and liquid-saturated foam balls. The static con tact of s…
