Abstract: Dry electrode-based wearable electroencephalography (EEG) systems are susceptible to motion artifacts caused by changes in the electrode-skin impedance (ESI) that can prevent practical ambulatory use. This work presents a 6.8 μW AFE that simultaneously and continuously measures EEG and ESI on the same set of electrodes. This work achieves lower power and area than prior art that integrates EEG and Z-measurement and enables up to 19dB of motion artifact reduction in vivo from EarEEG experiments.
