A Household Multimodal Physiological Signals Monitoring System

This paper presents a household multimodal physiological signals monitoring system, which aims at health management without leaving home for the elderly, the weak and the chronical. The system is composed of sensor unit, AFE unit, ADC unit, digital control unit, data upload unit, and data management unit. The system is designed to allow sensing, conditioning, acquisition, transmission, and storage of single-lead electrocardiogram (sECG), left limb electromyogram (lLEMG), right limb electromyogram (rLEMG), and plantar ballistocardiogram (pBCG). The core functions of the system have been validated with 10 volunteers. Rich features, especially ECG-like segments, can be obviously observed in the acquired multimodal physiological signals, indicating that the system makes it possible to track long-term physiological variables and predict disease risk.
