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
