Abstract: The global elderly population is rapidly growing due to low birth rates and advances in medical technology. Most elderly people with dementia experience a loss of cognitive functions, such as thinking, emotional control, and memory, which interferes with their daily life and activities. Our research aims to develop a smart shoe for Elderly Tracking and Rescue System, consisting of two separate operations: the transmission unit and the receiving unit. In the transmission unit, a piezo-electric plate is placed in the shoe, generating energy through foot movement to power the system. This power drives the system to wirelessly transmit real-time location data using the low-energy ESP-Now communication protocol. In the receiving part, transmitted data is stored on a website with a graphical view, displaying location markers for easy visualization. Relatives can monitor the elderly person’s location by clicking on a marker, which opens Google Maps to show the exact position, enabling seamless and interactive tracking. Alerts are sent via SMS every 10 minutes to the elderly person’s relatives using a GSM module, including a Google Maps location link. Additionally, the GSM module ensures on-site data availability during power outages for uninterrupted operation. The system enhances the mobility and independence of elderly individuals through advanced technology, empowering them to move safely and confidently.
