Paper Abstract
This paper demonstrates a novel two-dimensional sensor packaging design to facilitate the use of fibre grating-based
sensors for simultaneous strain and temperature measurement. The width and height of a sensor package were optimized
to induce dissimilar responses from two co-located fibre gratings within the sensor head. Through an appropriate
calibration of both the strain and temperature coefficients of the individual fibre gratings used, both strain and
temperature can be accurately determined and their individual components separated by measuring the shift in their
respective Bragg wavelengths. This approach can not only ensure the robustness of the sensor head, but also offer the
necessary level of control over the differences between the coefficients, which allows for maximizing the accuracy of the
strain and temperature values determined from the sensor itself.
