Maternal Postpartum Monitoring with a Wearable Sensor (MOMS)
Official title: Maternal Obstetric Monitoring System (MOMS): a Postpartum Hemorrhage (PPH) Wearable Monitor
Funded at University of California-Irvine · NIH-11536966 · Data updated 2026-11-12
A wearable system called MOMS will continuously monitor multiple physiological signals in pregnant people to detect postpartum hemorrhage earlier than standard vital signs.

Who could benefit from this research
✓Could help
Pregnant people in the postpartum period at risk for or monitored for postpartum hemorrhage, in hospital or peri-hospital settings.
✕Less likely to help
Patients without postpartum hemorrhage or those not using wearable monitoring may not directly benefit.
What this research studies
This project aims to create and test a wearable device that records high-quality body signals from several sensors in one easy-to-wear patch or band. By analyzing these signals in real time, the device should identify early warning signs of postpartum hemorrhage before traditional vital signs become abnormal. The team will validate an alpha prototype with an integrated blood pressure sensor and CSI sensor, then define what the beta prototype needs for future development. The goal is to provide a robust tool for both hospital and ambulatory use to improve early detection and timely intervention.
Why it matters
Potential benefit: If successful, MOMS could enable earlier detection of PPH and faster treatment, potentially saving mothers’ lives.
How similar studies have gone: Previous studies suggest vital signs alone may miss early PPH signs, so this wearable approach is a novel extension with potential real-world impact.
