Abstract：In order to solve the problem of frequent falls in elderly caused by aging society and reduce the harm led by abnormal state such as falls, a wearable posture monitoring device based on inertial sensors has been designed.The device, based on the charac-teristics of posture calculation,could discriminate current posture by analyzing multiple motion features acquired through three-axis accelerometer, three-axis gyroscope and three-axis magnetometer.It not only could detect fallen state ,but also could monitor daily posture and position information of the wearer,count the number of footsteps and report data to the server through the GPRS network. The device was also equipped with vocal broadcasting function,which could broadcast weather information and regards came from serv-er.The test results show that the device can detect abnormal situations such as falls and send out alarms to concerned party instantly. The posture recognition accuracy is higher than 98%.
