摘要
根据反射型光电容积描记(photoplethysmography,PPG)技术原理设计了一款柔性非侵入式血氧传感器.光电元件贴装在柔性电路板上,使传感器可以更舒适、更紧密的贴合人体表面.环绕对称式的元件布局提高传感器的精度和稳定性.通过银-环氧树脂体系导电胶和钢网印刷工艺实现传感器中的机械和电气联接.测试结果表明:基于导电胶的改良封装工艺可以制备出功能正常的柔性血氧传感器,该传感器在多次弯曲后性能稳定,适合集成在可穿戴设备中.
A reflection-mode photoplethysmographic(rPPG)sensor has been researched for non-invasive physiological assessment through isotropically conductive adhesives(ICAs)based manufacture processes.Selected photodiodes and Light Emitting Diodes(LEDs)were mounted on a flexible printed circuit board(PCB),so that the sensor can fit the human body surface more comfortably and closely.The surrounding symmetrical element layout improves the accuracy and stability of the sensor.The trial rPPG sensors were successfully manufactured and evaluated in the house.The results gained from this study shown the functions of the sensor could be fully realized by ICAs.The preliminary outcome demonstrates the suitability for the wearable cardiovascular assessment.
