 Intrauterine fetal demise due to utero-placental insufficiency usually occurs between obstetric evaluations when the gestation is not being actively monitored. Rapid advances in the development of “wearable” physiologic monitors linked to smart phone apps allow us to envision novel methods for evaluating the health of a pregnancy, potentially allowing intervention before fetal death or damage from asphyxia occur. In this report, we describe efforts to develop a fetal ECG monitor that can be worn throughout the day to confirm fetal wellbeing.
