“…The signal is recorded by probes that can detect the mechanical vibrations caused by the fetal heart. Among the most popular sensing probes are microphones [5], but there are also other means of sensors based on optical fibers [6], accelerometers [7], or other alternatives [8]. However, besides the desired fPCG signal, the probes also record variety of unwanted signals that affect the resulting signal quality.…”

Fetal phonocardiography (fPCG) is receiving attention as it is a promising method for continuous fetal monitoring due to its non-invasive and passive nature. However, it suffers from the interference from various sources, overlapping the desired signal in the time and frequency domains. This paper introduces the state-of-the-art methods used for fPCG signal extraction and processing, as well as means of detection and classification of various features defining fetal health state. It also provides an extensive summary of remaining challenges, along with the practical insights and suggestions for the future research directions.

“…The recording of fetal heart sounds has been resurrected in the fetal phonocardiogram (fPCG) over the past few years. Compared to sporadic auscultation, this approach allows the digitization of heart sounds and therefore more accurate assessment and analysis based on computers [3]. In addition, unlike the CTG, it makes it possible to measure the variability of the heart rate and to detect certain additional features of the fPCG signal (e.g.sub audible noises, murmurs, etc.).…”

Auscultation is still one of the most basic analytical tools used to determine the fetal heart’s functional state as well as the first fetal well-being measure. It is called fetal phonocardiography (fPCG) in its modern form. The technique of fPCG is passive and can be used to track long-term. Robust signal processing techniques are required to denoise the signals in order to improve the diagnostic capabilities of fPCG. A linear filter is used to eliminate distortion and interference from the fPCG signals through conventional denoising techniques. This paper searched for optimal configuration of the wavelet based denoising system. Based on the experimental results, can be conclude that the signal should be decomposed on six levels. From this it can be seen that the lowest MSE (mean square error) value is the use of coiflets three with SURE threshold algorithm with hard threshold parameters.

“…Researchers have obtained test measures of the heart rate measurements. Kolarik et al studied low-cost devices for measurement of fetal heart rate consisting of a heart rate sensor using phonocardiography, an analog-digital converter, and a computer [26]. Hodge, Humnabadkar, and Bidwai developed a wireless heart rate monitoring and vigilant systems that consisted of a heart rate sensor using IRphotodiode, an Arduino microcontroller, NRF module, and a system detector [27].…”

Aromatherapy is an alternative treatment method that uses essential oil vapors from various plants inhaled for health therapy. It affects mood, reduces fatigue and anxiety, and stimulates relaxation. Relaxation is the process of relieving anxiety or stress. It is interpreted as a calm state with a normal pulse. When someone is stressful and anxious, the pulse is higher. Measuring the level of anxiety is done by measuring the heart rate. The research aimed to design an electric aromatherapy device equipped with Atmega 8-based heart rate monitoring as a therapeutic tool that can help reduce various kinds of health problems, one of which is anxiety or stress disorder. The test was carried out by comparing the values of the heart rate monitoring to a pulse oximeter. The oximeter was used as a reference to get high accuracy values. The device is expected to help reduce various kinds of health problems caused by heart problems.
