Many individuals suffer from ailments such hypertension that require frequent health monitoring. Unfortunately, current technology does not possess the ability for unobtrusive, continuous monitoring. This paper proposes estimation of pulse pressure based on pulse transient time determined from one non-contact, and one contact sensor: Doppler radar for non-contact detection of heart beat, and piezoelectric finger pulse sensor. The time delay between heart beat and finger pulse was determined using MATLAB software, and pulse wave velocity (PWV) was calculated. Finally, subjects' pulse pressure estimated using PWV was found to be in good agreement with pulse pressure measured using an off the shelf sphygmomanometer by reading and taking difference of systolic and diastolic blood pressure.
许多人患有诸如高血压等疾病，这些疾病需要频繁的健康监测。不幸的是，当前技术无法实现无干扰的连续监测。本文提出基于由一个非接触式传感器和一个接触式传感器确定的脉搏瞬态时间来估计脉压：用于非接触式心跳检测的多普勒雷达和压电手指脉搏传感器。使用MATLAB软件确定心跳与手指脉搏之间的时间延迟，并计算脉搏波速度（PWV）。最后，通过读取并计算收缩压和舒张压的差值，发现使用PWV估计的受试者脉压与使用现成血压计测量的脉压高度一致。
