Abstract:
In this study, we proposed and implemented a wireless electroencephalogram (EEG) measurement device using compressed sensing, utilizing random undersampling and only a 40 mm x 40 mm small thermoelectric generator (TEG) as the power source. The results of the 4x compression experiment revealed a reduction in the power of the microcontroller from 345 uW to 97 uW. This implies that a wireless EEG measurement device can operate well with a small TEG, even though the reconstructed signal is not inferior to the original signal, in which the average normalized mean square error is approximately 0.24.
