PDMS-Based Low Cost Flexible Dry Electrode for Long-Term EEG Measurement

In this paper, a novel flexible dry electrode for long-term electroencephalogram (EEG) measurement is presented. Though the standard wet electrodes (Ag/AgCl) were used widely, they have their own drawbacks, such as the need for conductive gel and skin preparation, which causes the user discomfort and is unsafe, and cannot fit the long-term EEG measurement. To overcome these drawbacks of the wet electrodes, a novel flexible dry electrode made of...
