A wearable health and safety monitoring systems for fall detection and emergency alert functionality

Abstract

The present invention is related to a wearable health and safety monitoring systems for fall detection and emergency alert functionality. The present invention relates to a smart IoT-enabled wearable fall detection and emergency alert system designed to enhance personal safety and provide real-time intervention in case of accidental falls or sudden emergencies. The system integrates an Arduino Nano 33 IoT microcontroller with inertial sensors accelerometer and gyroscope to continuously monitor the wearer’s motion and detect abnormal activities. Upon detecting a fall, the system immediately triggers an audible alert and sends real-time notifications to a connected smartphone, caregiver dashboard, or cloud platform using Bluetooth Low Energy (BLE) and optional Wi-Fi connectivity. The system also includes a manual emergency button and an optional voice-assist feature, allowing proactive or hands-free alert activation. With intelligent motion sensing, multi-modal notifications, energy-efficient operation, and a compact wearable form factor, the invention provides a reliable, scalable, and user-friendly solution for elderly care, personal safety, occupational health, and tele-assistance applications, ensuring rapid response, reduced risk of injury, and enhanced autonomy for users.
