AI-Enhanced Wearable Multi-Microphone Fetal Heart Rate Monitoring Belt with Maternal Heart Rate Differentiation

Case ID:
UA25-205
Invention:

This invention is for a wearable belt encapsulating a fetal heartrate monitoring device (FHR). It employs a multi-microphone array for differentiation of maternal and feta heartbeats and utilizes data from real-time signal processing in conjunction with AI to achieve precise fetal monitoring. The device features wireless connectivity, transmitting real-time data to a smartphone application where users can visualize fetal heart rate trends, receive AI-based alerts, and sync data with cloud storage for remote physician access. This non-invasive, hands-free, and AI-enhanced monitoring solution offers a safer, more accessible, and cost-effective alternative to traditional Doppler ultrasound and ECG-based fetal monitoring systems.

Background: 
Preterm birth complications are the leading cause of death among children under 5 years of age, responsible for approximately 900,000 deaths in 2019. Doppler devices for fetal monitoring often require over 20 weeks of gestation for effective fetal heart rate detection, this system enhances weak signals leading to earlier fetal monitoring, as early as 14-16 weeks of gestation. This wearable fetal heart rate (FHR) monitoring system provides greater, more accurate heart rate detection capabilities with increased accessibility for pregnant individuals. 

Applications: 

  • Fetal heart rate monitoring system 
  • Pregnancy monitoring
  • Maternal healthcare
  • Obstetrics


Advantages: 

  • Advanced fetal heart rate monitoring system
  • Adaptive noise cancellation
  • AI-driven anomaly detection
  • Non-invasive, hands-free, accessible system
  • Remote monitoring
  • Transmits real-time data
  • More cost effective than traditional monitoring systems
