Why the study?
Can a contact-less microwave doppler radar system accurately detect heartbeat rate and heart rate variability compared to an electrocardiogram?
Can a contact-less microwave doppler radar system accurately detect heartbeat rate and heart rate variability compared to an electrocardiogram?
A contact-less microwave doppler radar system can potentially detect heartbeat rate and heart rate variability, offering a non-invasive alternative to traditional ECG.
May support contactless radar feasibility for HR/HRV; hypothesis-generating and requires prospective validation before any clinical use.
This article presents a contact‐less system to detect the heartbeat activity from a distance of 1 m. The proposed system is based on using a vector network analyzer. Measurements are performed at 16 GHz for different power levels between 0 and −25 dBm. Results for two S‐parameters are obtained and compared to an electrocardiogram simultaneous signal in terms of heartbeat rate and heart rate variability.
