Accurate measurement of fluid flow velocities is challenging but essential in many
disciplines. Inspiration of possible measurement methods can come from nature, for example from
the lateral line organ of fish, which is comprised of hair cells embedded in a gelatinous cupula.
When the cupula is deflected by water movement, the hair cells initiate neural signals that generate
an accurate image of the fish?s surroundings. We built a flow sensor mimicking a hair cell, yet
coupled it with an optical detection method. Fluid flow bends the waveguide; this leads to a
measurable light loss that depends linearly on the waveguide deflection.
