OPTICAL-WAVEGUIDE BASED FLEXIBLE PRESSURE SENSOR

摘要

The present invention relates to an optical waveguide-based flexible pressure sensor which is an optical waveguide-based flexible pressure sensor with a structure of forming a grating layer on a waveguide without an electric wire. The optical waveguide-based flexible pressure sensor removes an art-factor like electromagnetic interference affecting a signal possible to flow in the electric wire, so as to increase accuracy in pressure measurement.
