Through this study, the investigators hope to determine the feasibility, signal quality, and measurement accuracy of wearable ultrasound for monitoring uterine activity and fetal wellbeing in the peripartum setting. The knowledge gained may support development of future wearable ultrasound systems capable of providing hands-free, longitudinal, quantitative and non-invasive information about uterine contraction patterns, as well as fetal anatomy, cardiac activity and circulation, thereby complementing existing intrapartum monitoring technologies.",[26,27,28],"Pregnancy - Labor Monitoring","Labor and Childbirth","Fetal Heart Rate Tracing",[30,31,32,33],"tocometry","fetal heart tracing","labor contraction measurement","ultrasound","NOT_YET_RECRUITING","2026-10-06",{"date":37,"type":38},"2026-10-13","ACTUAL",{"date":40,"type":20},"2026-11",{"date":42,"type":20},"2027-11",{"name":44,"class":45},"Stanford University","OTHER"]
