Summary: Seals can detect prey up to 180 m away using their flow-sensing whiskers. The undulating morphology of their whiskers reduce vortex-induced vibrations, making them highly sensitive to biologically relevant flow stimuli. This study proposes a mathematical framework to accurately recreate the undulating geometry of harbor and grey seal whiskers. The research also reveals that grey seal whiskers have lower vortex-induced vibrations compared to harbor seal whiskers and a smooth cylinder, making them an ideal template for the biomimetic design of VIV-resistant underwater structures. Additionally, neighboring whiskers in an array influence each other, leading to increased vibrations and a possible signal-strengthening effect.

Summary: Triboelectrification between metals, polymers, and semiconductors was investigated, revealing a universal mechanism involving both electrostatic induction and dynamic junction modulation. The outputs of triboelectrification exhibited four current/voltage peaks, two of which were attributed to electrostatic induction effects and determined by surface state densities and electron affinity differences between the materials. The other two peaks were associated with dynamic junction modulation effects and determined by charging exchange between surface states and depletion regions. While metals and polymers showed no modulation of depletion regions, only the peaks induced by electrostatic induction were observable. Semiconductors, on the other hand, exhibited additional peaks induced by junction modulation when in contact with any material type. These findings provide valuable insights for developing high-performance triboelectric nanogenerators.
