Agar/NaCl tissue phantom mimicking electrical properties of human body in low frequency spectrum: A Brain-Computer Interface Inside Your Earphones

This report details the design and development of an agar/NaCl gel-like tissue phantom mimicking the electrical properties of wet human skin. The skin phantom provides a reliable, reproducible testing ground for dry-contact polydimethylsiloxane (CNT/PDMS) electrodes, with the aim of recording electroencephalograms (EEGs) and stimulating brain...
