Alzwatch: Iot-Based Wearable System for Monitoring Vital Signs and Tracking Alzheimer’s Patients

Abstract

Over 55 Millions around the world are living with dementia, and the count is likely to grow 78 million by the year of 2030. One of the biggest issue Alzheimer’s patients face is wandering which means they leave home without remembering their way back, which is dangerous and stressful for themselves and their families. Traditional methods like manual supervision and basic GPS trackers aren’t having enough facilities which lacks of smart monitoring because they don’t provide real-time alerts or monitor the patient’s health. For this, we developed an efficient solution using a smart wearable device integrated with IoT, real time GPS and health tracking. It tracks the patient’s location in real time using GPS, and if they leave a predefined safe zone, an automatic alert message is sent to the caregiver’s mobile app. It also monitors vital signs like heart rate (SpO₂), body temperature, and fall detection using a gyroscope sensor. If there’s any abnormal fluctuation, the system automatically notifies the caregiver. Plus, caregivers can even send a reminder message with just one click telling the patient to return home. With cases of dementia increasing every year, a smart, automated system like this is necessary to ensure safety and quick emergency response. Our system helps reduce caregiver stress, keeps patients independent for longer, and provides a real-time safety solution for Alzheimer's care.
