Optical Fibre Pressure Sensors in Medical Applications.

Poeggel S, Tosi D, Duraibabu D, Leen G, McGrath D, Lewis E - Sensors (Basel) (2015)

Bottom Line: This article is focused on reviewing the current state-of-the-art of optical fibre pressure sensors for medical applications.The small dimensions of optical fibre-based pressure sensors, together with being lightweight and flexible, mean that they are minimally invasive for many medical applications and, thus, particularly suited to in vivo measurement.This paper presents an overview of the recent developments in optical fibre-based pressure measurements with particular reference to these application areas.

ABSTRACT
This article is focused on reviewing the current state-of-the-art of optical fibre pressure sensors for medical applications. Optical fibres have inherent advantages due to their small size, immunity to electromagnetic interferences and their suitability for remote monitoring and multiplexing. The small dimensions of optical fibre-based pressure sensors, together with being lightweight and flexible, mean that they are minimally invasive for many medical applications and, thus, particularly suited to in vivo measurement. This means that the sensor can be placed directly inside a patient, e.g., for urodynamic and cardiovascular assessment. This paper presents an overview of the recent developments in optical fibre-based pressure measurements with particular reference to these application areas.

Mentions: Poeggel et al. [87] (2014) achieved in vivo bladder and abdominal measurements in patients, using a differential measurement technique, which allowed the simultaneous measurement of urodynamic pressure in a 1.6-mm (5 Fr) catheter, as well as abdominal pressure (Figure 8a,b). In a study published in 2015 [161] (Figure 8c), the technique was extended using an EFPI sensor with integrated FBG (i.e., measuring pressure and temperature with a single sensor), creating an optical fibre pressure and temperature sensor (OFPTS). Furthermore, two sensors were placed in a single 1.6-mm (5 Fr) catheter, with a separation of 1 cm. This technique facilitated a true differential pressure measurement.
