A miniaturized wearable and radio-communicating fall detection device for the elderly. It consists of a miniaturized radio-communicating embedded electronic device patched to the person. It has to date no equivalent around the world in the area of health parameters monitoring of subjects with a health status demanding a permanent survey. It overcomes both ergonomic and reliability deficiencies of the existing products by developing a new generation miniaturized fall detector device integrated into a whole fall detection system able to manage a fall event from its detection, to its cause assessment and medical services intervention.
