Shark skin-inspired surfaces

Definition

Shark skin-inspired surfaces refer to materials and designs that mimic the unique structure of shark skin, known for its exceptional hydrodynamic properties. These surfaces are characterized by tiny, tooth-like scales called dermal denticles that reduce drag and turbulence in water, leading to enhanced movement efficiency. This biomimetic approach is utilized in various applications, including sports equipment and medical devices, to improve performance and reduce energy consumption.
