RESEARCH ON CALIBRATION OF PHYSIOLOGICAL PARAMETERS BASED ON WEARABLE DEVICES
Objective: Focusing on the low accuracy of physiological parameters of wearable devices in the market,research on the calibration method of physiological parameters of wearable devices.Methods: First,our study based on the smart bracelet performance tests in the initial stage intends to take advantage of the test results of the volunteers wearing smart bracelet to analyze physiological characteristic parameters of human walking,and establish human motion models.Secondly,we get acceleration and angular velocity signal in different states of motion with models,to design the virtual prototype of gait simulator,and the gait of the gait simulator is simulated and controlled.Once more,according to the principle of photoelectric sensor that wearable device can measure volume pulse wave,a simulator was designed to match the shape of the wearable device and output the heart rate and blood oxygen signal,the gait simulator and the heart rate and blood oxygen simulator are integrated into simulator of physiological parameters.Finally,using the principle of coupling pressure measurement with air bag and simulator of noninvasive blood pressure brought together to solve the problem of calibration systolic blood pressure,diastolic blood pressure and other dynamic parameters do not disassemble the wearable device.Results: Using the simulator of physiological parameters of design can identify accuracy of gait,heart rate and blood oxygen at different movement of testing the wearable devices.The use of airbag coupling pressure detection principle can do not disassemble the wearable equipment for systolic blood pressure,diastolic pressure accuracy test is also feasible.Conclusion: Calibration of physiological parameters of wearable devices can reflect its accuracy,and to evaluate its quality.
