Advancing Intelligent Product Design: Integrating Information Technology and Digital Health Solutions

Abstract

This study addresses the integration of advanced information technology and digital health concepts through the design of an intelligent health monitoring product. This product is engineered to monitor critical physiological parameters in real time, catering to the increasing demand for health management solutions that are both accessible and accurate. Utilizing a polymer moisture-sensitive resistive sensor, the device is capable of monitoring respiratory status by detecting humidity changes during nasal breathing. Additionally, a reflective photoelectric pulse wave detection method is employed to measure heart rate and blood oxygen saturation. The system incorporates sophisticated signal processing techniques, including analog-to-digital conversion, to enhance the accuracy of blood oxygen saturation monitoring. A dual conductive layer resistive sensor further refines the detection mechanisms, enabling precise heart rate monitoring. The integration of these technologies into a single device was meticulously designed and tested, demonstrating the product’s capability to deliver reliable physiological data. Practical application tests reveal that the device achieves an exceptionally low absolute error in oxygen saturation measurements—ranging from 0.002 to 0.015 during sedentary conditions and 0.003 to 0.017 during controlled breathing scenarios. These findings confirm the device's high accuracy and reliability in real-world settings. By providing timely and precise health data, this intelligent product significantly enhances individual health monitoring, offering a practical solution for continuous assessment of key physiological indicators.
