摘要：

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.
