摘要：
The present invention relates to a device for measuring thermal conductivity comprising at least two fiber optics, at least one encapsulation, in which the first fiber optic comprises at least one section with an etched Bragg grating and is configured as a temperature measurement sensor. The second fiber optic comprises at least one section doped with calcium oxide nanoparticles, wherein the second fiber optic is configured as a thermal conductivity measurement sensor. Encapsulation involves at least one section with an etched Bragg grating and at least one section doped with calcium oxide nanoparticles.
