Nano-electromechanical systems (NEMS) sensor devices that utilize thin electrically conductive membranes, which can be, for example, graphene membranes. The NEMS devices can have a trough shape (such as a serpentine shape arrangement) of the electrically conductive membrane. The thin, electrically conductive membrane has membrane-structures disposed upon it in an array of cavities. These membrane structures are between the thin, electrically conductive membrane and the main membrane trace. Such an arrangement increases the sensitivity of the NEMS sensor device. The electrically conductive membrane can be controllably wicked down on the edge of the oxide cavity to increase the sensitivity of the NEMS sensor device. Such NEMS sensor devices include NEMS sensor devices that are well suited to applications that measure magnetic fields that, operate below 10 kHz, such as brain-computer interfaces.
