MOBILE BALLISTOCARDIOGRAPHY BASED ON ACCELEROMETERS USING ADDRESSABLE FIBER BRAGG STRUCTURES

Abstract

Abstract. Noninvasive monitoring and long-term monitoring of vital signs are essential requirements for early diagnosis and prevention for many reasons, one of the most important of which is improving the quality of life. This article discusses the main methods of taking a ballistocardiogram based on fiber optic technologies. The developments of a method for taking a ballistocardiogram in a stationary and dynamic position using addressable fiber Bragg structures are considered. Based on the analysis, a method for taking a ballistocardiogram in a stationary position using addressable fiber Bragg structures was developed, which allows getting rid of a complex and expensive interrogator. We present a sensor proposed by us for solving the problems of quasi-stable and mobile BCG, which was developed on the method based on three parallel fibers and AFBG, which allows eliminating the problems of dynamic BCG measurements.
