Abstract

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 9.24×10-2 nm/mm.
