| Popis: | 104 The Heart Rate Variability (HRV) wearable device and Accelerometer with body activity information using the brainwave recording module can analyze the sleep quality through the parameter, t(LFPmin), defined as the start time for deep sleep. The t(LFPmin) can be obtained from one of the HRV parameters, LFP. Using the information from the HRV wearable device and Accelerometer, we can find the time difference between the LFPmin and the body activity stable signal as t(LFPmin). The body activity stable signal via the acclelerometer bracelet/ watch can represent the status entering the extremely relaxed during sleep. The duration of the body activity stable should not be any physical movement or change. The standard sleep analysis, Polysommnography (PSG) should ultilize a lot of testing equipments to bring sleep disorders via the body’s complex wire connection for a number of test equipments. The PSG analysis is difficult to use in the daily life’s sleep analysis. The LFP(Low Frequency Power) of HRV parameter can be used as a reference to determine the quality of sleep. Using the EEG brainwave data and heart rate variability information during sleep, we can analyze the sleep status for improving the quality of sleep. |
