In-drop capillary spooling of spider capture thread inspires hybrid fibers with mixed solid–liquid mechanical properties
An essential element in the web-trap architecture, the capture silk spun by ecribellate orb
spiders consists of glue droplets sitting astride a silk filament. Mechanically this thread …

Elastocapillary bending of microfibers around liquid droplets
We report on the elastocapillary deformation of flexible microfibers in contact with liquid
droplets. A fiber is observed to bend more as the size of the contacting droplet is increased …

Liquid droplets act as “compass needles” for the stresses in a deformable membrane
We examine the shape of droplets atop deformable thin elastomeric films prepared with an
anisotropic tension. As the droplets generate a deformation in the taut film through capillary …

Auxiliary soft beam for the amplification of the elasto-capillary coiling: towards stretchable electronics
A flexible fiber carrying a liquid drop may coil inside the drop thereby creating a drop-on-
fiber system with an ultra-extensible behavior. During compression, the excess fiber is …

Static wetting of a barrel-shaped droplet on a soft-layer-coated fiber
A droplet can deform a soft substrate due to capillary forces when they are in contact. We
study the static deformation of a soft solid layer coated on a rigid cylindrical fiber when an …

Elastocapillary coiling of an elastic rod inside a drop
Capillary forces acting at the surface of a liquid drop can be strong enough to deform small

Drop-on-coilable-fibre systems exhibit negative stiffness events and transitions in coiling morphology
We investigate the mechanics of elastic fibres carrying liquid droplets. In such systems,
buckling may localize inside the drop cavity if the fibre is thin enough. This so-called drop-on …
