Abstract

This article describes an analysis of the use of fiber-optic technology in biomedical applications, specifically for the monitoring heart rate of the pregnant (mHR) and fetal (fHR). Authors focused on the use of Fiber Bragg Grating (FBG) and Fiber-Optic Interferometers (FOI). Thanks to the utilization of conventional method so-called cardiotocography (CTG), the mortality of newborn babies during delivery has decreased. Generally, among disadvantages of this method, there is a high sensitivity to noises caused by the movement of a mother, and it is connected with the frequent transfer of ultrasonic converters. This method is not suitable for a long-term continuous monitoring due to a possible influence of ultrasonic radiation on the fetus. Use of fiber-optic technology offers many advantages, for example, use measuring probes based FBG or FOI does not represent any additional radiation burden for the pregnant woman or fetus, fiber-optic measurement probes are resistant to technical artifacts such as electromagnetic interferences (EMI), thus they can be used in situations where it is impossible to use classic methods, e.g. examination by magnetic resonance (MR) or in case of delivery in water. The article describes the first experimental knowledge of based on real measurements.
