Sample EEG recording
This EEG Sample shows a comparison between wet passive gold cup electrode (blue curve, used as the reference), and ThinkPulse (red curve) at the same location on occipital O1.
Signals were also compared in spectral readings: they show similar performances. This is made possible thanks to our active electronics, which provides important noise limitation.
Low noise sensor
ThinkPulse active EEG sensor SNR has been compared with respect to a state of the art EEG wet electrode. Each data presented on the histogram (channel 1 & 2) is the result of a 4 measurements average. The “Average” tag is the result of both channel 1 & 2 averaging.
The wet electrodes considered here is a gold-plated one, used with conductive paste for application on the scalp. SNR is given as a power ratio in Alpha-Waves spectral band. It has been measured with respect to Conscious Labs ThinkPulse User Kit.
