Wearable health-monitoring system requires keeping the balance between energy consuming and user's real-time service demands with continuous sensing, wireless communication and processing. In this paper, we present a design framework for an Energy Efficient Wearable Health-monitoring System (EEWHMS). EEWHMS uses smartphone as a central unit to process data from wearable sensors, with event-driven energy management strategy to save energy. State transitions and continuous being still of user is used to adjust duty cycle of the system. We present the design, implementation, and evaluation of EEWHMS, which collects user's information with accelerometer and physiological sensors, and sends it to an Android phone by Bluetooth. According to evaluation of power of Bluetooth chip, CPU load of smartphone and response time when emergency happened, the system demonstrates its capability to keep balance between real time and long term sensing in an energy-efficient manner.
