Abstract
Bacterial cellulose (BC), a natural biomaterial, offers unique properties for implantable neural interfaces. This work introduces "Brainmask," a micro-electrocorticography (micro-ECOG) electrode using a BC film substrate and parylene-C microelectrodes. Brainmask ensures precise microelectrode positioning on nonplanar surfaces and maintains long-lasting signal quality, demonstrated through acute (at least one hour) and in vivo (one week) recordings.
