The prioritization of Patient Safety is the central driver behind the shift toward non-invasive fetal monitoring technologies. While internal monitoring using a fetal scalp electrode provides highly accurate data, it introduces a risk of minor scalp injury and a slight, though manageable, risk of uterine infection, and is only feasible once the amniotic membranes have ruptured. These drawbacks have fueled R&D into external solutions that maintain high clinical accuracy without invasive procedures.

Non-invasive fetal electrocardiography (NIFECG) and other wireless wearable systems address these safety concerns directly. They utilize passive sensing, avoiding the need for skin abrasion or internal contact, thus eliminating the risks associated with invasive methods. These modern devices are also designed to be independent of maternal body mass index (BMI) and movement, reducing the incidence of unreliable tracings and subsequent unnecessary clinical interventions. By improving signal clarity and minimizing procedure-related risks, the newest technologies contribute significantly to safer outcomes for both mother and fetus.
