Title:
STRESS SENSOR
Document Type and Number:
WIPO Patent Application WO/2017/078083
Kind Code:
A1
Abstract:
This stress sensor comprises: a light source which emits light of a first wavelength and light of a second wavelength that is different from the first wavelength; and an optical waveguide on which the light of the first wavelength and the light of the second wavelength is incident. The optical waveguide is provided with: a core in which a fluorescent dye is dispersed; and a cladding which covers the circumference of the core. The fluorescent dye is excited by the light of the first wavelength and emits light of a third wavelength; and the second wavelength and the third wavelength are in the visible light range.
