摘要
为了改善传统脉搏、血氧测量方式以及适应人们对设备可携带的要求,通过对压电薄膜的研究,选择合适的无源压电薄膜传感器和无创反射式血氧模块,采用ARM Cortex—M3微型处理器,整合了温湿度传感器、显示报警及无线通讯等模块,制成了一种可穿戴式生理数据检测仪。通过测试,仪器检测的数据与正常标准值的平均相对测量误差在1.0%之内,满足测量要求。实验表明:该检测仪制作简单,测量准确,携带方便,对临床以及个人脉搏及血氧检测具有一定的实际指导意义。
In order to improve traditional pulse,blood oxygen measurement method,and adapt to portable requirements of equipment through study of piezoelectric thin film,select appropriate passive piezoelectric thin film sensor and invasive reflective blood oxygen module,using Cortex—M3 ARM micro processor,integrated temperature and humidity sensor,display alarm and wireless communication module,fabricate a wearable physiological data detector. Through test,average relative measuring error of instrument test data and normal standard value is within1 %,which meets requirement of measurement. Experiments show that the detector is simple,accurate,easy to carry,and has some practical guidance for clinical and personal pulse and blood oxygen detection.
