Abstract: A vibration sensor for a fluid environment includes a vibrissa that can be positioned in the fluid environment. The vibrissa is joined to a cantilever body having magnets positioned thereon. Cantilever body is supported by a resilient support member in an interior hollow within a housing. Support member allows movement of body in two dimensions while supporting the body in a third dimension. Magnetic sensors corresponding to the magnets on the body are positioned on the housing for detecting movement of the body caused by the vibrissa. In various embodiments, the support member can be a membrane shielding the housing interior from environmental fluid flow.
