| Abstract: | In recent years, fiber optic sensors have shown great potential in biomedical applications, especially in cardiac health monitoring. This study aims to explore the feasibility of measuring vital signs (focusing on heart rate) using a six-hole optic fiber sensor. The use of optical fiber structure sensors aims to improve the collection and filtering process of heart rate signals, thereby overcoming the limitations of traditional monitoring techniques. We used a six-hole fiber to build the sensor, collect signals, and then process the data through MATLAB. We tested and experimentally evaluated the performance of the six-hole optic fiber sensor in a real environment. The results showed that the sensor has high sensitivity and good stability. Through using this sensor, clear BCG signals can be achieved. Compared with traditional methods, the six-hole fiber optic sensor retains the clarity of the BCG signal while also ensuring the accuracy of the measurement. The research results demonstrate the feasibility of six-hole fiber optic technology in measuring vital signs such as heart rate. Experiments show that the sensor is capable of continuous, real-time non-invasive cardiac monitoring and is expected to become an important component of wearable devices and personalized medical systems. This non-invasive real-time detection may play a key role in the early detection and emergency of cardiac abnormalities, making a significant contribution to the development of personalized medicine and improving the patient testing experience. In summary, our study demonstrated the effectiveness of six-hole fiber optic sensors in electrocardiogram monitoring and their potential for widespread application. By addressing current challenges in sensor design and data processing, this research will help promote innovative applications of fiber optic sensors in the biomedical field and demonstrate their role in improving health monitoring technology. |
