Abstract

This work demonstrates a micro anemometer monolithically integrated onto a cleaved optical fiber via two-photon polymerization microfabrication. The sensing mechanism features an aerodynamically driven rotor which spins in response to an incident flow. Light exiting the core of the optical fiber is reflected back into the fiber core at a flow-dependent rate as the blades pass by. The device operated successfully over a range of 9.35–24.28 LPM using Nitrogen gas, and achieved a linear response of 706 ± 43 reflections/LPM over a range of 10.97–11.79 LPM.
