Sleep analysis system and method for analyzing sleep thereof
First Claim
1. A sleep sensing apparatus for attachment to a subject and cooperating with an analysis device, the sleep sensing apparatus comprising:
- an electrocardiogram (ECG) signal collector for collecting an ECG signal associated with the subject;
a multi-axial accelerometer for detecting a multi-axial accelerometer signal associated with the subject;
a wireless transmitting unit; and
a control unit coupled to the ECG signal collector, the multi-axial accelerometer, and the wireless transmitting unit, to control the wireless transmitting unit to transmit the ECG signal and the multi-axial accelerometer signal to the analysis device,wherein the analysis device performs a first operation using the multi-axial accelerometer signal to obtain an acceleration variation, and the analysis device determines whether the subject is on a sleep status or an awake status according to the acceleration variation, andthe analysis device performs a second operation using the ECG signal to analyze heart rate variability (HRV) thus to obtain an HRV analysis result which comprises a low frequency component and a high frequency component, and the analysis device determines whether the subject is in a first sleep mode or a second sleep mode according to a ratio of the low frequency component to the high frequency component.
