Wake-induced ‘slaloming’ response explains exquisite sensitivity of seal whisker-like sensors
TL;DR: In this article, the authors identify and illustrate a novel flow mechanism, causing a large-amplitude "slaloming" whisker response, which allows artificial whiskers with the identical unique undulatory geometry as those of the harbour seal to detect the features of minute flow fluctuations when placed within wakes.
Calibration and validation of a harbor seal whisker-inspired flow sensor
TL;DR: In this paper, a flow sensor inspired by the harbor seal's whiskers has been calibrated in a towing tank and tested at sea, showing the vibration amplitude in the cross-flow direction to range from 0.1 to 0.6 times the whisker diameter, depending on the flow direction.

On the stabilization of leading-edge vortices with spanwise flow
TL;DR: In this article, the influence of spanwise flow on the development and stabilization of leading edge vortices on a foil (without rotational acceleration) has been investigated, and the plunging swept wing/fin geometry used in this study, characteristic of fish-like tails, has been found to be insufficient in the stabilization of LEVs.

TL;DR: In this article, a sensor with the undulatory geometry of a harbor seal whisker has been designed, fabricated, and characterized for use as a mechanical sensor of flow velocity, and a waterproof design with a pressure housing has been made, allowing the sensor to operate at depth.

TL;DR: In this article, a biomimetic whisker sensor is designed by mounting the model on a four-armed flexure, allowing it to freely vibrate, and using strain gauges to measure deflections at the whisker base.
