AB - Portable health monitoring device could benefit the life quality of patients as well as decreasing health
care costs. Monitoring Electrocardiogram (ECG) and Impedance Cardiography (ICG) simultaneously
can help evaluate cardiovascular disease comprehensively. However most of the ICG monitoring devices
are only used in clinical measurement instead of family monitoring. Based on the above concern, this
paper designed a portable health monitoring device based on Bluetooth Low Energy (BLE) which
is valued for its ultra-low power consumption for long-term continuous non-invasive cardiac activity
monitoring by measuring ECG, ICG, acceleration and angular acceleration of body. There are mainly
four advantages of this device: 1) High integration: ECG, ICG, acceleration and angular acceleration can
be monitored in a single circuit; 2) Low power consumption: The device can monitor continuously for
over 83 hours when powered by a 3.7 V lithium polymer battery with 1000 mAh; 3) Small size: The area
of the PCB is only 30 mm × 40 mm, so it is very easy to be attached to clothes; 4) Wireless communication:
The acquired data can be transmitted to a personal computer or a smart phone wirelessly via Bluetooth.
Different body postures (upright or supine) can result in change of ICG signal, which can be used for
adjusting patients' hemodynamic parameters.
