Abstract: This study explores the use of Fiber Bragg Grating (FBG) sensors encapsulated in stainless steel for precise temperature measurements in a soft probe applicati on. Encapsulation enhances temperature sensitivity while minimizing strain interference, a common challenge in FBG sensor applications. Experimental results showed minimal wavelength shifts and temperature errors, demonstrating the effectiveness of the metallic capillary in decoupling strain effects from temperature measurements. The calibration curve confirmed high temperature sensitivity and low strain sensitivity. This method offers a reliable solution for precise temperature measurements in environments where strain can introduce measurement noise.
