A Bluetooth-Based Portable Design Device with Wireless Power Module for Electrocardiogram and Respiration Measurement

Abstract

This paper presents compact design and implementation of a portable device for application of continuous Electrocardiogram(ECG) and respiration measurement in the field of dynamic health monitoring. Bluetooth technique is used for data transmission between portable device and acquisition node such as computer or smart phone, given its advantages of low power consumption and easy wireless connection. The device also includes a wireless power module for charging the lithium polymer battery with the charging current up to 300mA, which makes power supply much more conveniently. Measurement of ECG and respiration is implemented by two electrodes layout solution and ADS1292R which enable the system design at significantly reduced size(60mm*40mm), power, and overall cost. Experiments are carried out with appropriate work parameters as sample rates and resolution. The results show that our device can accurately acquire the ECG and multiple respiration states..
