|Title:||A FABRY-PEROT SENSOR PROTOTYPE FOR LOW-PRESSURE MEASUREMENTS|
|Authors:||Paulo Roriz Oliveira|

|Abstract:||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.
