Smart Menstrual Pain Relief Wearable Belt with Hydration & Nutrition Assistance

Objective To design and develop a wearable health monitoring system that continuously measures vital parameters such as heart rate, SpO₂ level, and body temperature using multiple sensors integrated with an ESP32 controller. To provide real-time alerts and therapeutic responses through buzzer alerts, vibration feedback, and Peltier-based pain management, along with IoT-enabled notifications to authorized personnel via the Blynk platform. Results The sensor accuracy of the proposed system was evaluated by comparing sensor readings with standard medical devices. The heart rate sensor and pulse sensor demonstrated consistent readings under normal conditions. Minor variations were observed due to sensor placement and environmental factors. The temperature sensor provided stable and reliable measurements when placed in contact with the skin surface. Data collected during testing indicated that the sensors were capable of detecting physiological changes effectively. The monitoring system successfully recorded heart rate fluctuations during pain episodes. Sensor data was displayed clearly on the LCD screen and transmitted to the mobile application without significant delay. Calibration procedures improved measurement accuracy and reliability. Overall, the sensor system demonstrated satisfactory performance for wearable health monitoring applications. These results indicate that the system is capable of providing accurate physiological monitoring during menstrual cycles.
