| Abstract: | A new type of cantilever beam structure which consists of two kinds of polymeters is designed,using single fiber Bragg grating(FBG) to achieve simultaneous measurement of temperature and strain.This sensor used the equal strength cantilever beam with two kinds of polymer materials,which can solve the cross-sensitive issue of pressure and temperature measurement.When the sensor is simultaneously influenced by pressure and temperature,the reflection spectrum of the fiber Bragg grating is split int... |
