在多个位置测量身体的位移，可以观察到心脏脉搏波的传播，这是非接触式血压测量的重要一步。本研究探讨了使用在人体两个位置测量的皮肤位移波形进行血压测量的可行性。为了评估所提出的方法的准确性，本研究使用了一对激光位移传感器，使精确的脉冲渡越时间测量。通过比较两种传感器的位移波形，评估脉搏传导时间与血压之间的关系。实验证明，该方法可以估计出5.1mmHg的血压，其误差与普通袖带式血压计的误差相当。
Measurement of the body's displacement at multiple positions allows heart pulse wave propagation to be observed; this is an important step toward noncontact blood pressure measurement. This study investigates the feasibility of performing blood pressure measurements using skin displacement waveforms measured at two positions on a human body. To evaluate the accuracy of the proposed approach, this study uses a pair of laser displacement sensors to enable precise pulse transit time measurement. By comparing the displacement waveforms from the two sensors, the relationship between pulse transit time and blood pressure was evaluated. It is demonstrated experimentally that the blood pressure can be estimated with accuracy of 5.1 mmHg, which is equivalent to the error of an ordinary cuff-type blood pressure monitor.
