WiFi signals can measure heart rate - with no wearable device needed, reveals new research.

Engineers showed their technique is effective even with the lowest-cost WiFi devices .

Heart rate is one of the most basic and important indicators of health, providing a snapshot into someone’s physical activity, stress and anxiety, hydration level, and more.

Traditionally, measuring heart rate requires some sort of wearable device, whether that be a smart watch or hospital-grade machinery.

But new research shows how the signal from a household WiFi device can be used to monitor heart rate with state-of-the-art accuracy - without the need for a wearable.

The proof of concept work shows that one day, anyone could take advantage of the non-intrusive WiFi-based health monito
