[EN] In this work, we obtained chirped Bragg gratings by post-coating uniform poly (methylmethacrylate) (PMMA)
microstructured polymer optical fiber Bragg gratings (POFBGs) with an UV cure adhesive. The main advantage of ...
[EN] Human physiological signal monitoring is a key factor in diagnosing health conditions, such as monitoring heart rate and respiration. To meet the increasing monitoring requirements, such as safety, economy, and equipment ...
[EN] In this study, we investigated plastic optical fiber (POF) pressure sensors embedded in mattresses to measure
respiration and heart rate for sleep performance monitoring. The signal is amplified in the circuit using ...
