Objective: Fetal heart rate (FHR) is critical for perinatal fetal monitoring. However, motions,
contractions and other dynamics may substantially degrade the quality of acquired signals …

In wearable optical sensing applications whose target tissue is not superficial, such as deep
tissue oximetry, the task of embedded system design has to strike a balance between two …

Fetal electrocardiogram (fECG) or photoplethysmogram (fPPG) devices are being
developed for fetal heart rate (FHR) monitoring. However, deep tissue sensing is challenged …

We present a method, referred to as Deep Harmonic Finesse (DHF), for separation of non-
stationary quasi-periodic signals when limited data is available. The problem frequently …

Quasi-periodic signal separation poses a significant challenge in wearable systems with
limited data, particularly when the measured signal, influenced by multiple physiological …

Fetal monitoring is essential to ensure the well-being of both mother and fetal. This paper
reviews the existing non-invasive fetal well-being monitoring based signal techniques. The …

Individuals with long-term respiratory disorders must monitor their oxygen saturation on a
constant basis. Real-time monitoring and patient mobility, however, are limited by traditional …
