Dispositivo para identificar quedas de pessoas idosas pelo uso do princípio de acelerometria

Abstract

During a fall, the body assumes an increasing temperature variation that occurs when it collides with the ground. And this interference variation can be measured by a sensor called an accelerometer. This work developed a device in the form of a bracelet for use in the elderly capable of detecting and identifying the pattern of this event. It also has a panic button to call for quick help and a system for identifying the use of the device through an amplified optical sensor that identifies cardiac arrests. The detection algorithm was developed considering the analysis of a graphic drop and the threshold method for event identification. The device achieved advanced results in detection, where all data is uploaded to the cloud so that event notifications can be issued to those responsible through computer programs or smartphone applications.
