提出了一种新型的双光纤布拉格光栅传感器结构，该结构集成了机械应力放大和共模抑制温度补偿。应力放大允许测量非常低的致动器力，例如由小横截面波纹管产生的致动器力，用于作为大气压力传感器操作。我们展示了一个压力传感器的范围为800-1100 hPa和0.1 hPa的分辨率。
A novel dual-fibre Bragg grating sensor structure is described, incorporating integrated mechanical stress amplification and temperature compensation by common mode rejection. Stress amplification allows the measurement of very low actuator forces, such as generated by small cross section bellows, for operation as a barometric pressure sensor. We demonstrate a pressure sensor range of 800–1100 hPa and a resolution of 0.1 hPa.
