MUMBAI, India, Jan. 2 -- Intellectual Property India has published a patent application (202541123043 A) filed by G. Pullaiah College Of Engineering And Technology, Kurnool, Andhra Pradesh, on Dec. 5, 2025, for 'iot-based health monitoring and emergency alert system.'
Inventor(s) include A. Swetha Rani; B. Sulochana; Gude Ramarao; Dr. T. Tirupal; K. Uma Maheswari; Alluru Sreevani; and Dr. Pasuluri Bindu Swetha.
The application for the patent was published on Jan. 2, under issue no. 01/2026.
According to the abstract released by the Intellectual Property India: "In the modern world, where individuals are occupied with busy routines, ensuring the safety and health of elderly or chronically ill patients at home has become a pressing concern. Manual monitoring is not always practical, especially when immediate attention is required. To address this issue, this project proposes the design and implementation of a cost-effective, real-time IoT-based Smart Health Monitoring and Emergency Alert System using the NodeMCU ESP8266 microcontroller. The system incorporates multiple sensors including the MAX30100 Pulse Oximeter to monitor heart rate and blood oxygen saturation levels, the DHT11 sensor to measure body temperature, and a capacitive touch sensor that allows the patient to initiate emergency alerts manually. These biomedical parameters are continuously collected and processed by the NodeMCU and transmitted over Wi-Fi to the Blynk Cloud, enabling seamless remote monitoring through the Blynk mobile application. The system also includes an LCD display for local readings, a buzzer, and LED indicators to signal abnormal conditions instantly. If any parameter goes beyond a predefined threshold or if the touch sensor is triggered, an alert is immediately sent to caregivers or family members via push notifications, ensuring prompt medical response. The integration of IoT allows real-time data visualization, efficient tracking, and accessibility from anywhere, thus enhancing the quality of healthcare services provided remotely. The system was tested and found to deliver accurate results with minimal delay, performing comparably to commercial health monitoring devices. Its compact design, wireless capabilities, and user-friendly interface make it suitable for use in homes, especially during critical times such as the COVID-19 pandemic, where reducing physical contact is essential. By combining affordability, scalability, and functionality, this project effectively demonstrates the potential of IoT in transforming traditional healthcare into a more connected, automated, and responsive system."
