In this article, a low-cost fiber optic sensor (FOS)-based system is proposed for the long-term stable measurement of ballistocardiography (BCG), which can be used to analyze short-term heart rate variability (HRV). The core part of the system is a single-mode fiber-based Mach–Zehnder interferometer...
