This paper proposes a sensor for simultaneously measuring temperature and strain using a microfiber Bragg grating (MFBG), half of which is coated with polymer polydimethylsiloxane (PDMS) and encapsulated inside a couple of U-shape glass grooves, while the other half is bare. Due to the different thermal-optic coefficient, elastic-optic coefficient, and cross section structural dimension, the two reflection bands from the encapsulated part of the MFBG and the bare MFBG section show different behaviors to temperature and strain. The sensitivity t...
