一种可穿戴式多参数心脏活动监测设备的设计
Design of a Wearable Multi-Parameter Cardiac Activity Monitoring Device
摘要
Abstract
Electrocardiogram (ECG), phonocardiogram (PCG) and ballistocardiogram (BCG) can reflect the heart activities from different aspects. We designed a wearable device that synchronously collected these three physiological parameters. In this device, nRF52832 Bluetooth Low Energy SoC was selected as the main control chip. The digital microphone (MP34DB02) was used to collect PCG signal, the ADS1191 ECG was used to simulate front-end collection of ECG signal, and the accelerated module was utilized to capture the BCG signal. The size of the device was 110 mm×34 mm×10 mm, with weight of 32 g. The data of the device installed in the ECG electrode buckle could be collected by pasting two ECG electrode in the appropriate parts of the human body. The bluetooth low energy used for data transmission had advantages of low power consumption. Besides, the device equipped with 75 mA rechargeable lithium battery, which could record the ECG data for 20 hours. The device is small in size and easy to use. It is suitable for family daily care.关键词
