Wavy Whiskers in Wakes: Explaining the Trail‐Tracking Capabilities of Whisker Arrays on Seal Muzzles (Adv. Sci. 2/2023)

Wavy Whiskers in Wakes It is known that seals can detect prey up to 180 m away using their flow‐sensing whiskers, which feature undulating morphologies that reduce vortex‐induced vibrations. In article number 2203062 by Xingwen Zheng, Ajay Giri Prakash Kottapalli, and co‐workers, through fluid‐structure interaction studies and experimental investigations involving seal whisker arrays mounted on 3D‐printed microelectromechanical systems sensors, the vibration characteristics of the whisker array and the interaction between neighboring whiskers in steady flows and fish‐wake‐like vortices are explained.
