Fiber optic sensor (FOS) has become more and more popular since it can perform unique functions that conventional sensors cannot. For example, an FOS can be embedded inside carbon fiber composite for fatigue tests or embedded in concrete bridges or dams for structural integrity tests. Due to the small size, FOS can be applied to places that are off-limits to other sensors, such as on the computer flip-chip Ball Grid Array substrate for qualification bending test, or on a catheter to measure bending radius. The purposes of this proposal are to develop specific FOSs for many important applications, including: i)FOS arrays for strain and bending measurement of steering artificial muscle catheter; ii)FOS for yield strength and tensile strength of friction stir welding alloy; iii) FOS arrays for detecting crack initiation and propagation of carbon fiber composite materials; and iv) FOS high speed impact test.

光纤传感器（FOS）由于具有传统传感器无法实现的独特功能而越来越受到人们的青睐。例如，FOS可以嵌入碳纤维复合材料中进行疲劳测试，或者嵌入混凝土桥梁或大坝中进行结构完整性测试。由于体积小，FOS可以应用于其他传感器无法使用的地方，例如在计算机倒装芯片球栅阵列基板上进行合格弯曲测试，或在导管上测量弯曲半径。该提案的目的是为许多重要应用开发特定的FOS，包括：i）用于转向人工肌肉导管的应变和弯曲测量的FOS阵列; ii）用于摩擦搅拌焊接合金的屈服强度和拉伸强度的FOS; iii）用于检测碳纤维复合材料的裂纹萌生和扩展的FOS阵列;以及iv）FOS高速冲击测试。
