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.
