A new approach to measuring displacement and temperature simultaneously by use of a specially designed isosceles triangular cantilevered beam as a strain agent is demonstrated. A fiber Bragg grating epoxied onto the beam surface is experimentally demonstrated to have a temperature sensitivity of ∼0.113 nm/°C below 60°C and a displacement sensitivity of 9.24 × 10-2nm/mm.
