Development of a mobile pulse waveform analyzer for cardiovascular health monitoring

Noninvasive pulse waveforms contain rich pathophysiological information of cardiovascular system. It is hereby a tradition of interest to implement risk stratification by pulse waveform monitoring and analysis. In contrast to conventional computer- or network-based solutions, we attempt to accomplish pulse waveform monitoring and analysis within a self-contained mobile platform. It adopts a compact biosensor for pulse waveform acquisition. The collected signals are then submitted to a core board for pulse waveform processing and analysis. In addition, the core board coordinates user interaction and network communication too. Such compact pulse waveform analyzer is of great help for cardiovascular health monitoring at home. A carefully designed evaluation has been undertaken within our research group. The results confirmed its prospect in home healthcare.
