TL;DR: This work uses flexible epicortical and intracortical arrays of graphene solution-gated field-effect transistors (gSGFETs) to map cortical spreading depression in rats and demonstrates that gSGFETS are able to record, with high fidelity, infraslow signals together with signals in the typical local field potential bandwidth.

TL;DR: In this article, the operation of solution-gated field-effect transistors (SGFETs) and characterizing their performance in saline solution were discussed and compared with the performance of state-of-the-art neural technologies.

TL;DR: In this paper, the authors demonstrate the fabrication of flexible arrays of Graphene SGFETs on polyimide, a biocompatible polymeric substrate, and demonstrate the recording of cell action potentials from cardiomyocyte-like cells.

TL;DR: Channel regions nearby the source and drain terminals are found to dominate the total noise for gate biases close to the charge neutrality point (CNP), revealing for the first time the strong correlation between this gate dependence and the residual charge which is relevant in the vicinity of this specific bias point.
