Dream time estimation by wireless ECG telemetry system

This paper illustrates the design and implementation of ECG telemetry system used to automatically estimate the dream time of a health subject. The dream time estimation has been done by acquiring variance of heart rate variability in sleep cycle. The implemented system has low power consumption and of small size (2.5cm x 3cm). Using ECG telemetry system, the estimation of dream time is easier and faster than conventional method such as polysomnography by EEG, EMG or EOG. The experimental results enlighten that the subject experienced the dream 4 times in the whole night and by adding the time of each stage we will achieve the total dream time. The total dream time is 500 second. Compare it with commercial product shows the 2.91% error in result.
