At different stages of life, from embryonic to postnatal, varying oxygen concentrations
modulate cellular gene expression by enhancing or repressing hypoxia‐inducible …

Fetal acidosis is one of the main concerns during labor. Currently, fetal blood sampling
(FBS) has become the most accurate measurement of acidosis detection. However, it is …

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 …

Intrapartum fetal well-being assessment relies on fetal heart rate (FHR) monitoring. Studies
have shown that FHR monitoring has a high false-positive rate for detecting fetal hypoxia …

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 …

Noninvasive transabdominal fetal pulse oximetry can provide clinicians critical assessment
of fetal health and potentially contribute to improved management of childbirth. Conventional …

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

This paper presents a low-power wide-swing current mirror light emitting diode (LED) driver
designed for an ultra-low power pulse oximeter. The presented driver can regulate red …

We present an algorithm for live tracking of quasi-periodic faint signals in non-stationary,
noisy, and phase-desynchronized time series measurements that commonly arise in …

Significance Using functional near-infrared spectroscopy (fNIRS) in bottlenose dolphins
(Tursiops truncatus) could help to understand how echolocating animals perceive their …
