摘要:: 针对指部脉搏信号检测易受体动和血流灌注影响使信号质量降低的问题，提出耳后脉搏信号检测，该检测位置有运动幅度小、血流灌注稳定、佩戴方便、易隐藏等优点。脉搏传感器使用反射式，且其封装结构通过3D扫描、打印，个人定制为耳廓型，使传感器与检测部位最大程度贴合，从而提高日常生活中脉搏信号检测的稳定性。将同步检测的指部脉搏信号作为参考信号以验证耳后脉搏信号检测系统的有效性。结果表明，耳后与指部脉搏信号之间存在较好的一致性与线性关系，因此所研制的脉搏信号检测系统稳定可靠，为日常生活中人体健康状态的监护提供一种有效途径。

Abstract:: Abstract: The detection of the pulse signal behind the ear is proposed to solve the problem that the detection of finger pulse signal is susceptible to body movement and blood perfusion. Selecting the area behind the ear as the detection site has the advantages of small movement range, relatively stable blood perfusion, convenient wearing and easy to hide. The pulse sensor is reflective and its package structure is customized to the auricle through 3D scanning and printing, making the sensor fit with the detection site to the maximum extent, thus improving the stability of pulse signal detection in daily life. The synchronously detected finger pulse signal is used as a reference signal to verify the effectiveness of the proposed system for detecting the pulse signal behind the ear. The results show that there is a good consistency and linear relationship between the pulse signal behind the ear and finger pulse signal. The developed pulse signal detection system which is proved to be stable and reliable provides an effective way for monitoring human health in daily life.
