Sebaran Regangan Pernapasan Pada Bagian Belakang Tubuh Manusia Menggunakan Serat Kisi Bragg
Fiber Bragg Grating sensor is one of the optical components that can be used in monitoring human respiratory strain, because FBG has a high sensitivity to strain. The purpose of this study is to design the FBG sensor to determine the respiratory strain on the back of the human body. The strain (ε) value was calculate at four respiratory conditions, namely normal without oxygen flow, normal using oxygen flow, activity without oxygen flow, and activity using oxygen. The FBG sensor media is affixed to 25 positions on the back of an adult woman, with an Optical Sensing Interrogator as an input and data from the FBG reflection as an output with a wavelength of 1550 nm. In this study, it was found that the greatest strain was in the middle of the back with a vertical direction, namely position 18 at coordinates of (3.2). Under normal conditions without oxygen flow experienced by object 1 with a value of 9.555 × 10-5 ε, normal conditions using oxygen flow experienced by object 3 with a value of 11.541 × 10-5 ε, activity conditions without oxygen flow experienced by object 3 with a value of 9.927 × 10-5 ε, and activity conditions using oxygen flow experienced by object 3 with a value of 10.713 × 10-5 ε. The addition of oxygen flow in the body might increase the strain that occurs when breathing. This shows that the FBG sensor is more effectively used in conditions with the addition of oxygen flow.
