Revolutionizing carotid pulse analysis: a novel approach with custom designed neck band

Healthcare could undergo a major transformation with the incorporation of non-invasive sensors into wearable technology. This is due to these sensors' ability to provide instant monitoring of vital signs. Could be rewritten as Photoplethysmography (PPG) is a non-invasive technique that uses a small LED and photo sensor to detect the carotid pulse. Transcranial Doppler (TCD) is another non-invasive technique that measures the velocity of blood flow in the carotid artery using high frequency sound waves. This pulse is an essential indicator of blood pressure and heart rate. The primary goal of our research is to create a neck band equipped with both PPG and TCD sensors to enable comprehensive and precise carotid pulse monitoring. This paper will detail the designing, developing, and testing stages of the neck band, as well as the integration of sensors. Additionally, we will present data acquisition, data processing, and analysis. Lastly, the demonstration of the neck band's effectiveness in a controlled environment will be discussed.
