Wearable device for real-time monitoring of human falls

This paper presents a wearable micro-sensing device for monitoring human body falls. It combines micro-sensors and digital data processing technologies, such that in real-time, it can monitor the user to get immediate help by sending an emergency message to an aid station at the moment of falling. The primary feature of this system is the micro sensor, with a horizontal sensor embedded inside a smart coat. Two kinds of micro-sensors are used for the system, one is a micro-mercury switch, and the other is an optical sensor to detect if the wearer is horizontal. With the new algorithms for movement behaviors judgment, the system has the ability to collect, analyze, and transmit data by monitoring the user’s body. In outdoor sports, the system sends information on body position and location, and an emergency message from the user to a specific guard in real-time.
