Summary: A new type of airflow sensor based on optical micro/nanofiber (MNF) has been proposed and realized, which utilizes a flexible polydimethylsiloxane (PDMS) cantilever embedded with a U-shaped MNF to achieve bending-dependent transmittance variation. By arranging four cantilevers in two orthogonal directions, omnidirectional airflow can be measured within a speed range of 15 m/s. The optimized cantilever design also allows for real-time monitoring and distinction of voice and respiratory signals with a resolution of 0.012 m/s, showing promising potential for health monitoring applications.

Summary: In this study, a micro-angle measurement scheme based on a pixelated metasurface is proposed. By utilizing the interaction between a C-band optical frequency comb laser source and the plasmonic metasurface, precise angle encoding and ultra-sensitive angular responses are achieved. Angle-dependent optical barcodes are created by controlling the dimensions of meta-atom structures and designing specific combinations of meta-pixels. This technique enables highly efficient acquisition of angle information and absolute angle measurement.
