Elastic Organic Crystals as Bioinspired Hair‐Like Sensors

“…The air swirls are limited to the surface area of the crystal which ensures a stable deformation. The position of the swirls and the crystal deformation normally depend on the fluid velocity [50] . Therefore, the higher the air flow velocity, the larger the flow separation along the tip of the crystal which improves the strength of the air vortices, bending the crystal further away.…”

“…The position of the swirls and the crystal deformation normally depend on the fluid velocity. [50] Therefore, the higher the air flow velocity, the larger the flow separation along the tip of the crystal which improves the strength of the air vortices, bending the crystal further away. From the perspective of pressure forces (Figure 4d), the crystal experiences a high pressure exclusively at the tip (on the right) while on the rest of the crystal surface, the pressure remains low (bottom section of the the crystal).…”

Collective stiffening of soft hair assemblies

“…To test these models within simplified frameworks, artificial hairy systems have been used. These usually consist of slender pillars anchored to a substrate, whose deflections are monitored optically under controlled stresses [15][16][17].…”
