An interferometric Fabry–Perot cavity based on hollow‐core ring photonic crystal fiber combined with a silicone diaphragm is proposed for low pressure sensing. The sensor exhibits a sensitivity of 0.086 nm/mmHg for a pressure range between 0 and 337.5 mmHg. These values are in the range of physiological pressures, such as intravascular pressure. © 2014 Wiley Periodicals, Inc. Microwave Opt Technol Lett 56:2981–2984, 2014
