Abstract The simultaneous acquisition of seismocardiographic (SCG) and ballistocardio-graphic (BCG) signals permits systematic investigation of cardiovascular vibration propagation along the thorax-periphery axis, offering substantial potential for hemodynamic analysis. This research develops a wearable monitoring apparatus integrating dual sensing modalities: a microelectromechanical system (MEMS) triaxial accelerometer for SCG recording and a polyvinylidene fluoride (PVDF) piezoelectric sensor array for BCG detection. The embedded signal conditioning circuitry enables synchronized SCG-BCG capture, with subsequent preprocessing performed through computational algorithms. Experimental results confirm the system’s capability to reliably acquire synchronized cardiomechanical signals while maintaining measurement consistency across varied sensor placements. This technological solution demonstrates applicability in diverse clinical settings ranging from primary care institutions to domiciliary healthcare environments.
