A Highly Reliable Wearable Device for Fall Detection

A late treated fall may cause irreparable damage or even the death of a human being. This problem gets worse with the older ages of the person suffering the fall. Solutions to this problem do exist in the market but do not appropriately address the reliability of using the proposed devices. None of the existing solutions clearly present their capabilities in terms of testing, operation safety and fault tolerance. This work not only gets structured the offline and online tests to which the device should be exposed, but also proposes the use of hardware and software redundancy to provide for a more reliable solution for the problem. A prototype of a wearable device for fall detection has been developed, that provides for safe operation and tolerate faults, while delivering very low current consumption and low cost, those that are essential specifications to meet the market demands for wearable devices
