How Radar-Based Health Monitoring Works

Radar technology, traditionally used for detecting speed and obstacles, is being repurposed for health monitoring. By emitting electromagnetic waves that bounce off objects, radar can detect minute chest movements caused by breathing and heartbeats. This allows for the measurement of vital signs from a distance, even through blankets, clothing, and walls 1

Advantages Over Other Remote Monitoring Technologies

While camera-based systems using infrared light can monitor some health parameters, they face limitations such as obstruction by clothing, inadequate lighting, and potential inaccuracies due to different skin tones. Radar overcomes these challenges:

1. It can penetrate obstacles like blankets and clothing
2. It's not affected by lighting conditions or skin tone
3. It maintains patient privacy due to low-resolution imagery
4. It operates at safe frequency and power levels 1
