Integrated accelerometry-based Fall Detection System

Background

Falls have an increasing social and economic impact,specially in the developed countries, as life expectancyof our elderly rises dramatically. Fall-related injuriesincreases morbidity, mortality and premature use of healthcare services reducing also the time the elderly can liveautonomously at their own homes. Fall detection systemsmay notify emergency responders when no one apart fromthe injured is present. However, their real-world applicationis limited by a number of factors such as high false positiverates, low-compliance, poor usability and short batterylifetime. In order to improve these aspects we developed afall detection algorithm with a low false alarm rate to beused in a miniaturized 3D accelerometer integrated in a beltbuckle - the actibelt® - developed at the Sylvia LawryCenter for Multiple Sclerosis Research . The following thesisconsist of implementing the fall detection algorithm in themicrocontroller of the accelerometer and programming anAndroid-based application in order to link the actibelt®to a smart phone for fall detection management and notification.
