摘要

无创心电图(BCG)信号是记录由于心跳和血液流经大动脉而引起的身体运动。这个信号提供了足够的信息来计算心率及其随时间的变化。本文提出了一种低成本电子系统的原型设计，用于记录由三轴加速度计和陀螺仪获得的BCG信号。系统的设计使用了Arduino开发板，9轴MPU-9250传感器(加速度计、陀螺仪和磁力计)，以及免费软件RealTerm。该系统通过USB端口连接到一台个人计算机，从那里管理整个系统。建立了系统的模型，并成功地用任意信号进行了测试，检查了系统的正确功能，并将数据记录在文本文件中供以后分析。

Adquisición de señales balistocardiográficas con Arduino

The noninvasive Balistocardiogram (BCG) signal is the recording of body movements due to heartbeat and blood flow through major arteries. This signal provides enough information to calculate the heart rate and its variations over time. The present paper proposes the design of a prototype of a low-cost electronic system to record the BCG signals acquired by means of a triaxial accelerometer and gyroscope. For the design of the system, an Arduino development board, the 9-axis MPU-9250 sensor (accelerometer, gyroscope and magnetometer), and the free software RealTerm are used. The system is connected by a USB port to a personal computer from where the entire system is governed. A model of the system was built and tested successfully with arbitrary signals, checking the correct functioning of the system and recording the data in a text file for later analysis.
