一种心率检测仪的低功耗与抗静电设计
Design of a Low-Power and Antistatic Heart Rate Monitor
摘要
Abstract
Objective To develop a noninvasive and continuous heart rate monitoring product, so as to monitor patients with cardiovascular diseases in their daily life. Methods Under the human thighs, the vascular pulsations were acquired to calculate the heart rate value by the piezoelectric film sensor which was placed on an office chair. As a core of operation and control, STM32F411 was used to achieve low power programming. Then, transient protection devices and embedded software monitoring module were designed to resist interference causing by the electrostatic discharge. Results In the three operation modes, the device has excellent performance of energy consumption and the ESD immunity meets the YY 0505-2012 standard requirements. Conclusion This monitor is easy to use, as well as safe, stable and energy-friendly. It provides a reliable and practical solution for cardiac monitoring at home.关键词
