«In a typical electrical circuit approach, spin current is driven by
voltage difference across the structure.
One of the challenges to scaling up the process, he notes, will be developing new materials for fuel cell membranes that won't quickly become clogged with the chemical byproducts of bacterial activity, which would cut down on the flow of ions that help maintain
the voltage difference across the membranes.

voltage change
across electrodes as 2 mA current and the bi-temporal montage provided higher
voltage differences than the occipitofrontal montage.
