In the era of digital transformation and artificial intelligence, smart biosensors have emerged as essential tools in medical diagnostics. These sensors play a vital role in monitoring vital signs, enabling early detection of both chronic and acute diseases.<br />Types of Smart Biosensors:<br />Smart biosensors vary depending on their function and placement. Common types include:<br />Electrocardiogram (ECG) sensors<br />Non-invasive glucose sensors<br />Biological temperature sensors<br />Blood oxygen sensors (SpO2)<br />Neural sensors for brain activity (EEG sensors)<br />Smart biosensors track subtle changes in vital signs in real-time, allowing for preventive action before health conditions worsen. This advancement is especially crucial in managing diseases such as diabetes, cardiovascular disorders, and neurological conditions.<br />Sustainable Development Goal (SDG 3) Contribution:<br />These sensors support Goal 3 of the SDGs: "Ensure healthy lives and promote well-being for all at all ages" by:<br />Promoting early diagnosis and reducing premature deaths<br />Lessening the burden on healthcare systems<br />Enhancing the quality of life for chronic patients<br />Conclusion:<br />Smart biosensors are foundational in shaping a sustainable healthcare future. By integrating technology with medicine, we can move toward a more proactive, aware, and healthy society.<br />Al-Mustaqbal University the first university of Iraq .
