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.
