摘要
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.
