cat whisker
Sensitive facial bristle
Cat whisker refers to the stiff sensory hairs (vibrissae) that grow from a cat's muzzle, used for spatial awareness and detecting air currents.
In early radio technology, a cat whisker was a thin wire that made contact with a crystal to detect radio signals—the delicate adjustment required gave the component its name.
She adjusted the cat whisker until the station came in clearly.
