TL;DR
This paper reviews recent advances in solid capillarity, focusing on how surface tension causes large deformations in soft solids and discussing key open questions in the field.
Contribution
It synthesizes recent research on surface tension effects in soft solids and identifies critical questions for future exploration.
Findings
Surface stresses can induce significant deformations in soft solids.
Recent experimental and theoretical advances have expanded understanding of solid capillarity.
Key open questions remain about the mechanisms and applications of surface tension in soft materials.
Abstract
Soft solids differ from stiff solids in an important way: their surface stresses can drive large deformations. Based on a topical workshop held in the Lorentz Center in Leiden, this Opinion highlights some recent advances in the growing field of solid capillarity and poses key questions for its advancement.
