Wearable EEG via lossless compression

Annu Int Conf IEEE Eng Med Biol Soc. 2016 Aug:2016:1995-1998. doi: 10.1109/EMBC.2016.7591116.

Abstract

This work presents a wearable multi-channel EEG recording system featuring a lossless compression algorithm. The algorithm, based in a previously reported algorithm by the authors, exploits the existing temporal correlation between samples at different sampling times, and the spatial correlation between different electrodes across the scalp. The low-power platform is able to compress, by a factor between 2.3 and 3.6, up to 300sps from 64 channels with a power consumption of 176μW/ch. The performance of the algorithm compares favorably with the best compression rates reported up to date in the literature.
