Summary: This paper presents and characterizes for the first time an integrated and robust fiber-optic FabryPerot (FP) humidity sensor based on the metal-organic framework (MOF) material FIR-53, along with its implementation method. By rationally connecting the single-mode fiber (SMF) with FIR-53 using polydimethylsiloxane (PDMS), the proposed sensor monitors the spectrum peak shift caused by humidity change. The experiments demonstrate that the sensor has a sensitivity of 315 pm/% relative humidity (RH) in the range of 10%-90% RH, as well as good linearity, reversibility, long-time stability, and antihigh-temperature interference resistance.

Summary: In this paper, a miniature high-temperature fiber-optic sensor based on tip-packaged Fabry-Perot interferometer is proposed and demonstrated. The sensor is insensitive to changes in external refractive index and maintains good temperature sensing characteristics. Two packaging methods, using hollow core fiber (HCF) or single mode fiber (SMF), are proposed. The temperature sensitivities of these sensors increase due to the non-linear thermo-optic coefficient (TOC) of silicon. The repeatability and stability of the sensors are verified, making them suitable for practical engineering applications.

Summary: This study presents a true multimodal pulse wave (PW) sensor that integrates a piezoelectric forcecardiography (FCG) sensor and a photoplethysmography (PPG) sensor for simultaneous mechanical-optical measurements of PWs from the same body site. The preliminary results show a delay between the PWs recorded by the PPG and FCG sensors, but high cross-correlation indices were observed. Further investigation is needed to understand the physical origin of the delay and validate the results in a larger subject cohort. This research paves the way for the development of wearable, integrated sensors and sensor fusion approaches to improve PW monitoring.
