Many new technologies in obstetrics & gynaecology (Obs-Gyn) now allow continuous, real-time, remote monitoring of mothers, fetuses, and gynecologic health parameters. These technologies fall under Digital Health, FemTech, Internet of Medical Things (IoMT), AI, and wearable sensors.
Below is an overview of the latest technologies/devices used for real-time online monitoring.
1. Remote Fetal Monitoring Systems (Home-based CTG / NST)
These devices allow continuous fetal monitoring from home while data is transmitted to the hospital.
Example
- INVU Remote Fetal Monitoring Platform
- Novii+ Wireless Patch Solution
Technology
- Wireless abdominal sensors
- Doppler or fetal ECG
- Cloud data transfer to hospital EMR
- Smartphone app for patient
Parameters monitored
- Fetal heart rate
- Maternal heart rate
- Uterine contractions
- Non-stress test (NST)
Example: INVU platform enables physicians to perform remote NST and view live fetal traces during teleconsultation.
Clinical use
- High-risk pregnancy
- Pre-eclampsia monitoring
- Post-date pregnancy
- Reduced fetal movement
2. Wearable Fetal ECG Sensors
A major innovation is continuous fetal ECG monitoring using wearable patches or belts.
Example
- HeartSync Wearable Fetal ECG
Technology
- Abdominal ECG electrodes
- AI-based signal processing
- Cloud analytics
These systems continuously monitor fetal and maternal heart activity and send alerts if abnormalities occur.
Advantages
- Early detection of fetal distress
- Continuous monitoring outside hospital
- Reduced hospital visits
3. Smart Pregnancy Wearables
These are consumer-level or medical wearables used during pregnancy.
Example
- Ava Fertility Tracker Bracelet
Sensors include
- skin temperature
- pulse
- heart rate variability
- breathing rate
- sleep pattern
The bracelet predicts fertile window and reproductive health trends using physiological signals.
Future use
- ovulation monitoring
- early pregnancy detection
- hormonal rhythm tracking
4. Uterine Electromyography (UEMG) Monitoring Devices
These are advanced devices measuring uterine electrical activity.
Example
- PreTel Pregnancy Monitoring System
Technology
- Uterine EMG sensors
- contraction mapping
- cloud monitoring
These devices can detect regional uterine contractions and improve management of preterm labor and labor progress.
5. AI-Enabled Pregnancy Monitoring Platforms
Modern systems combine wearables + AI decision support.
Features
- real-time risk prediction
- fetal distress detection
- anomaly alerts
- tele-obstetrics
AI algorithms analyze fetal heart rate patterns and maternal signals to detect complications earlier.
6. Smart Textiles (E-Textile Pregnancy Monitoring)
A very new technology.
Concept
- Sensors embedded into maternity clothing.
Monitors
- ECG
- uterine EMG
- muscle activity
These electronic textiles can continuously record maternal and uterine signals while remaining comfortable for long-term use.
7. IoMT Pregnancy Monitoring Kits
Used especially in community or rural maternal health programs.
Typical kit includes
- Bluetooth BP monitor
- digital glucometer
- hemoglobinometer
- fetal heart rate Doppler
- weight scale
Data is transmitted to doctors through mobile apps and cloud dashboards.
8. Tele-Obstetrics Platforms
A new care model combining:
- remote monitoring devices
- video consultation
- AI triage
- EMR integration
Doctors can monitor:
- fetal parameters
- BP in pregnancy
- gestational diabetes
- high-risk pregnancies
9. Smartphone-Based Obstetric Monitoring
Emerging solutions use smartphone sensors + AI apps.
Capabilities
- Doppler probes connected to phone
- fetal heart rate analysis
- decision support for midwives
- risk scoring
These tools are designed especially for low-resource settings and rural maternal care.
10. Continuous Maternal Monitoring Systems
Used in high-risk pregnancies.
Monitors include:
- maternal ECG
- oxygen saturation
- blood pressure
- glucose monitoring
- sleep & activity
These devices connect to central hospital monitoring systems.
