In this paper, the development of a wireless acquisition system (hardware and software) incorporating a novel high-resolution micro-electro-mechanical system (MEMS) accelerometer for SCG and BCG signals acquisition and data treatment is presented. The acquisition system uses a small accelerometer with a sensitivity of up to 0.164 µs/µg, a noise density below 6.5 µg/Hz and incorporates an electrocardiogram (ECG) sensor. The developed software enables the acquisition and real-time visualization of SCG and ECG signals and the calculation of metrics as well as data correlation with echocardiogram (ECHO) parameters. A preliminarily clinical study was performed to test the capability of the developed system. The high resolution of the MEMS accelerometer used provides a better signal for SCG wave recognition, enabling a more consistent study of the diagnostic capability of this technique in clinical analysis.
