A compact back-plaster sensor node for dementia and Alzheimer patient care

This paper presents a compact and highly integrated back-plaster sensor node equipped with seamless localization (in-door and out-door) based on assisted GPS and Bluetooth localization, activity classification and fall detection as well as a GSM module providing a GPRS connection to a server infrastructure for supporting dementia and Alzheimer patients in their daily life. The innovative and durable design as a hermetically rubber-sealed, waterproof and sanitizable back-plaster ensures optimum wearing comfort for the patient as well as reliable fall detection. In addition, combined with an internet server infrastructure the described plaster sensor node allows informing relatives or professional care in case of an emergency and help to enhance the quality of life by increasing patient's feeling of security.
