Abstract
As most people suffer from the sub-health problem or chronic diseases, research on sensing and managing personal health is growing rapidly. In this paper, a user-friendly smart watch, which can sense personal physiological data and physical activity is presented. Based on the device, a smartphone software is developed, this hardware and software system can gather data and monitor personal health from the aspects of physiological conditions and physical conditions. Compared with other systems, it has the advantage of providing raw sensing data and unobtrusively continuous sensing, which can bring new opportunity to pervasive personal health monitoring, and promote wearable computing research in health monitoring and disease prevention.
