This paper proposes a Fabry–Perot pressure sensor based on AB epoxy adhesive with ultra-high sensitivity under low pressure. Fabry–Perot interference, located between single-mode fiber (SMF) and hollow-core fiber (HCF), is an ultra-thin AB epoxy film formed by capillary action. Then the thick HCF was used to fix the HCF and SMF at both ends with AB epoxy adhesive. Experimental results show that when the thickness of AB epoxy film is 8.74 μm, and the cavity length is 30 μm, the sensor has the highest sensitivity. The sensitivity is 257.79 nm/MPa within the pressure range of 0–70 kPa. It also investigated the influence of the curing time of AB epoxy on the interference spectrum. Experiments showed that the interference spectrum peak is blue-shifted with the increase of curing time. Our study also demonstrated the humidity stability of this pressure sensor. These characteristics mean that our sensor has potential applications in the biomedical field and ocean exploration.

Different Diameters

The theoretical model is got for a new intrinsic Fabry-Perot interferometric fiber pressure sensor structure fabricated by single mode and multimode fibers with different diameters. The pressure response curves are simulated by Matlab software. The analysis results showed that the pressure sensitivity decreased with the diameter of multimode fiber increased at some area, but the sensitivity begins to increase when the diameter value is more than critical point. The high sensitivity can be still got by increasing fiber diameter.
