Tuning nonlinear waves in nonreciprocal active filaments
Sami C. Al-Izzi, Jack Binysh, Yao Du +2
The instabilities of slender structures power biological locomotion across scales, and offer a compelling method to actuate soft robots. Nonreciprocal elastic solids have been foun…
Nonreciprocal buckling makes active filaments polyfunctional
Sami C. Al-Izzi, Yao Du, Jonas Veenstra +5
Active filaments are a workhorse for propulsion and actuation across biology, soft robotics and mechanical metamaterials. However, artificial active rods suffer from limited robust…
Capillary Slinky: Equilibrium and Dynamics of Droplets in a Soft Spring
Bidisha Bhatt, Andreas Carlson
Springs can be found in many applications and biological systems, and when these are soft, they easily deform. At small scales, capillarity can induce a force leading to spring def…
The seed-carrying stalk of the linden diaspore ensures autorotating flight
Annette Cazaubiel, Andreas Carlson
The dispersal of seeds by wind is one of the most evolved mechanisms plants use to invade new territories. Linden trees grow diaspores with a curved bract acting as a wing, where t…
A trade-off between hydrodynamic performance and morphological bias limits the evolution of symmetric lattice animal wings
Sif F. Arnbjerg-Nielsen, Matthew D. Biviano, Annette Cazaubiel +3
Bristled and membranous insect wings have co-evolved despite apparently serving the same functionality. We emulate flight physics using an automated free-fall experiment to better…
