研究目的
To design a portable, noninvasive, low-cost multifunctional human physiological health index monitor based on photoelectric sensors to improve people's exercise style and meet the growing demand for intelligent fitness equipment.
研究成果
The research proposes a design scheme for a multi-functional fitness monitor based on a photoelectric sensor, which changes the traditional mode of fitness and provides real-time feedback of physiological indexes. The sensor has very good application prospects and far-reaching significance due to its noninvasive nature, low cost, and suitability for long-term health monitoring.
研究不足
The complexity of fully accomplishing an intelligent fitness system and the need for further completion and improvement of some procedures to meet the growing demand for intelligent fitness equipment.
1：Experimental Design and Method Selection:
The study involves the design of a multifunctional fitness monitor using photoelectric sensors to measure human physiological indexes. The methodology includes the use of photoelectric volume pulse waves for noninvasive detection.
2：Sample Selection and Data Sources:
The experiment involved 30 individuals, 20 men and 10 women, aged 20 to 70, from whom photoelectric volume pulse wave data were collected for 5 minutes.
3：List of Experimental Equipment and Materials:
The equipment includes a photoelectric sensor composed of a luminous diode (photoelectric emitter) and a photosensitive transistor (photoelectric receiver), operating at wavelengths of 660 nm and 940 nm.
4：Experimental Procedures and Operational Workflow:
The measurement of human fingertip volume pulse wave was conducted using an optical capacitance pulse wave polysomnography. The process involved ensuring the cleanliness of the photoelectric detector and minimizing movement to reduce errors.
5：Data Analysis Methods:
The data analysis involved calculating the light absorption ratio R of two wavelengths to determine blood oxygen saturation, using a formula that shows a linear relation between R and SaO2.
