Paper Abstract

In the paper, a simple and effective FBG sensor able to discriminate temperature from strain at a single point had been worked out, by sticking half of it on the fixed end of the polymer equivalent beam, leaving the other half free. The FBG was then separated into two segments with different temperature and strain coefficients, which composed the measuring matrix. The measuring sensitivities of temperature and strain of our setup are 9.58×10-6(1/°C) and 6.72×10-7(1/με) respectively. This device will have wide applications to discriminate between strain and temperature of sensing networks.
