Abstract: Due to the decline of physical fitness caused by diseases or other problems, there is a high occurrence probability of accidental falls among the older. In many cases, the injuries to the older will become much more serious as they can’t get timely help from others, some older even died. If the older wear some devices that can detect fall, and send alarm message to his/her relatives or healthcare institution, the security of the older can be ensured. This paper develops a wearable fall alarm system based on multi-sensor integration. The motion sensor is a tri-axial accelerometer, the features used to determine whether the user is fall are two kinematic parameters, and the detection algorithm is based on thresholds comparison. When a fall is detected, the system will get the user’s position from a GPS sensor, and a alarm message will be sent through the communication network. All the functions are integrated in a portable system.
