In this study, we developed an array sensor module to measure pulse wave of radial artery. To measure pressure, this module contains 7 piezoresistive sensors of the size of 1×1 mm. This sensor module is composed of a PCB for bonding sensor, PCB guide for wiring, silicon guide to keep its shape while PDMS coating, and PDMS layer protect fragile sensor and wire while faithfully transmitting the pressure of the patient's skin to the sensor. To test characteristic of pressure sensors in the sensor module, intra-chamber pressure was raised in 20mmHg step from 60mmHg to 220mmHg. The coefficient of determinant was r(2)>0.999. When the radial artery's pulse wave with developed sensor module was measured, pulse wave is clearly detected. In this study, developed array sensor module is appropriate to measure pulse wave.
在本研究中,我们开发了一种用于测量桡动脉脉搏波的阵列传感器模块。为了测量压力,该模块包含7个尺寸为1×1毫米的压阻式传感器。该传感器模块由用于粘贴传感器的印刷电路板(PCB)、用于布线的PCB导轨、在进行聚二甲基硅氧烷(PDMS)涂层时保持其形状的硅导轨以及PDMS层组成,PDMS层可保护易碎的传感器和导线,同时将患者皮肤的压力忠实地传递给传感器。为了测试传感器模块中压力传感器的特性,将腔内压力以20mmHg的步长从60mmHg升至220mmHg。决定系数为r²>0.999。当使用开发的传感器模块测量桡动脉的脉搏波时,可以清晰地检测到脉搏波。在本研究中,开发的阵列传感器模块适用于测量脉搏波。
