In this paper, we have proposed a self-powered wireless wearable health data tracking system based on an inertial rotary electromagnetic energy harvester. The whole system can be divided into three parts. The first part is the charging circuit. The energy harvester, which generate 1.65 V Root Mean Square (RMS) voltage and 32.15 mW power at the frequency of one foot while running (1 Hz), could convert kinetic energy of human motion into electrical energy to charge the Li-ion battery. The second part contains an Arduino Microcontroller Unit (MCU) and two sensors. These two sensors could monitor the temperature and the blood oxygen saturation (which can be used in calculation of heart rate) information of the feet and toes, respectively. In the last part, A Bluetooth module is applied to communicate with the MCU and send the health data to the cloud. Meanwhile, this data could be displayed on the smartphone. We also demonstrated the workflow of the whole system. With the energy harvester, the energy from human motion is used to drive sensors and the function of health monitoring is realized.
