Development of an integrated module using a wireless accelerometer and ECG sensor to monitor activities of daily living.
The objective of this work was to develop a wireless electrocardiogram (ECG) and acceleration detector powered by an imbedded battery. The module has a connector for a three-lead ECG socket and an embedded three-axis accelerometer. It also has an a secure digital (SD) memory slot and can store all data with 2 GB memory. The system transmits the data using a wireless module to measure ECG and an activity transition value. Using the correlation between accelerometer signal and ECG signal, the system can determine the activity assessment precisely and also detect cardiovascular abnormality.
