Abstract
Prolonged monitoring is more likely to result in an accurate diagnosis
of atrial fibrillation patients than intermittent or short-term monitoring.
In this study, we present an implantable ECG sensor to monitor atrial
fibrillation patients in real time. The developed implantable sensor is
composed of a micro controller unit, analog to digital converter, signal
transmitter, antenna, and two electrodes. The sensor detects ECG
signals from the two electrodes and transmits these signals to the
external receiver that is carried by the patient. The sensor continuously
transmits signals, so its battery consumption rate is extremely high.
To overcome this problem, we consider using a wireless power
transmission module in the sensor module. This module helps the
sensor charge power wirelessly without holding the battery in the
body. The size of the integrated sensor is approximately 0.12 x 1.18 x
0.19 inch. This sensor size is appropriate enough for cardiologists to
insert the sensor into patients without the need for a major surgery.
The data sampling rate was 300 samples/sec, and the frequency was
430 Hz for signal and power transmission.
