A Microwave Sensor for Contact-Free Measurement of Human Heart Rate

Abstract:

Measures of heart rate are widely used to assess the health state of human in clinic. Tranditional method uses eletrodes touching the body to monitor electrocardiography (ECG) .A micorwave sensor was disscused to remote sense the heart rate without touching human body. Comparison of heart rate derived from the microwave sensor and ECG demonstrated that there were no significant differences, which suggested this sensor may prove a practical alternative to ECG for heart rate measurement.
