Special Issue Information

Dear Colleagues,

Optical fiber sensing technologies have been proposed and demonstrated for a few decades because of their thin size, electromagnetic interference-free manner, flexibility, and embedded and remote sensing abilities. Therefore, structural health monitoring, robotics, and biomedical applications have superiority to use fiber optic sensors, which can detect strain, temperature, acceleration, and nearly every physical parameter measurement with high precision.

Specifically, recent advances in biomedical applications using fiber optic sensors have grown attractively. The optical fiber sensors with non-invasive and unconstrained monitoring enable early monitoring and detection of diseases and provide rapid, low-cost, and non-invasive diagnoses.

This Special Issue is focused on novel optical fiber sensors in the biomedical application for life sciences, biotechnology, and medical practice. We strongly encourage the submission of papers focusing on the keywords below. However, works on related topics will also be considered.

We developed a wearable swallowing assessment device using a hetero-core fiber-optic pressure sensor for the detection of laryngeal movement during swallowing. The proposed pressure sensor (comfortably attached to the skin of the neck) demonstrated a high sensitivity of 0.592 dB/kPa and a linearity of R2 = 0.995 within a 14 kPa pressure band, which is a suitable pressure for the detection of laryngeal movement. In addition, since the fabricated hetero-core fiber-optic pressure sensor maintains appreciable sensitivity over the surface of the sensor, the proposed wearable swallowing assessment device can accurately track the subtle pressure changes induced by laryngeal movements during the swallowing process. Sixteen male subjects and one female subject were evaluated in a variety of age groups ranging from 30 to 60 years old. For all subjects, characteristic swallowing waveforms (with two valleys based on laryngeal movements consisting of upward, forward, backward, and downward displacements) were acquired using the proposed wearable swallowing assessment device. Since the denoted time of the first valley in the acquired waveform determines the “aging effect”, significant differences in swallowing functions among the different age groups were ultimately determined based on the time of the first valley. Additionally, by analyzing each age group using the proposed device, due to p-values being consistently less than 0.05, swallowing times were found to exhibit statistically significant differences within the same groups.
