Among the innovative graduation projects of students in the Biomedical Engineering Department, which aim to provide smart, applied solutions serving the healthcare sector, a promising project titled “Leaf_CO2” was implemented under the direct supervision of Assistant Lecturer Zainab Sattar Jabbar. This project integrates medical technology with sustainable engineering design. About the Project and Innovation: The project involves the design and development of a smart, integrated medical device shaped like a leaf. It is designed to measure and monitor indoor air quality in hospital patient rooms. The device is distinguished by its ability to dynamically and interactively change color to reflect the health and environmental conditions of the air in real time, based on readings from its integrated sensor system. Methodology and Technical Mechanism: The device system relies on processing digital signals received from the patient's environment. Specifically, it utilizes: Precision sensors to measure carbon dioxide (CO2) levels, relative humidity, and ambient temperature. A smart microcontroller program analyzes data and instantly converts it into simple, color-coded visual indicators, enabling medical staff and their companions to immediately understand the quality of the surrounding environment without needing to read complex charts. This practical solution combines the functional precision of medical engineering with an aesthetically pleasing, nature-inspired design, reducing visual strain in medical rooms and supporting the trend towards smart, environmentally friendly medical devices. The project presentation received high praise from the scientific committees due to the importance of its practical application in improving the environment for patients with respiratory illnesses and those in intensive care. It provides a smart way to ensure optimal ventilation, promoting comfort, safety, and faster recovery. Project Objectives in Accordance with Sustainable Development: The “Leaf_CO2” project aligns with the Sustainable Development Goals supported by Future University, including: Goal 3 (Good Health and Well-being): by providing a safe and pollution-free healthcare environment to protect the health of patients and medical staff. Goal 9 (Industry and Innovation): By encouraging students to develop locally manufactured medical devices based on Internet of Things (IoT) technologies and smart embedded systems. Goal 11 (Sustainable Cities and Communities): By contributing to the development of "green and smart hospitals" that utilize advanced environmental monitoring systems.
