Abstract :
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. Bend sensors at the whisker base provide deflection information in four directions. A waterproof design with a pressure housing has been made, allowing the sensor to operate at depth, in a stand-alone configuration. Characterization was performed by correlating tip deflection to voltage output in each of the four sensors.
