“…The proposed fiber optic pH and glucose probe sensors have a sensitivity of 1.95 nm/pH and 3.25 nm/mM, respectively, with a high sensing stability and a relative standard deviation of about 2.5%. The proposed sensor provides linear sensing capabilities over a wide range of pH (2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12) and glucose (1 µM-1 M). The response time and recovery time of the proposed sensor are about 8 s and 9 s, respectively.…”

“…For example, they can be used to measure the blood oxygen saturation (S P O 2 ), blood glucose concentration, blood pH, and concentrations of biochemical molecules such as proteins, hormones, and drugs in the blood [4]. In addition, fiber optic sensors can also monitor one's pulse, blood flow rate, and viscosity in real time [5,6]. It provides clinicians with more comprehensive blood information, which helps in early diagnosis and disease treatment.…”

The advantages of optical fiber sensors include their miniaturization, strong anti-interference ability, high sensitivity, low cost, and fast response speed. They can be used for in situ detection in harsh environments, making them suitable for a wide range of applications such as blood detection and monitoring. This technology holds great potential for medical diagnosis and health monitoring, opening up new possibilities in the field. Coating technology plays a crucial role in enhancing the sensitivity and stability of optical fiber sensors, ultimately improving their measurement accuracy and reliability. This manuscript expounds the application status and progression of optical fiber sensors in the determination of blood glucose concentrations, blood pH, diverse proteins in blood, and physical properties of blood. The principle of optical fiber sensors and the application of coating technology for detecting varying targets are scrutinized in detail, with particular emphasis on the advantages and limitations of distinct design schemes. The adept amalgamation of optical fiber sensing technology and coating technology amplifies the adaptability of optical fiber sensors in diverse practical scenarios, thereby presenting novel instruments and methodologies for researchers in pertinent fields to augment their advancement and development.

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.
