Even if your sensor is um-sized, it's a goodish way above the cortex.
The only way to beat the distance and the shielding (for galvanic
potentials) is to remove the distance and the shield, which means
you have to get invasive. Miniaturization can't beat that, unless
we're talking nanoscale invasive devices, which are in situ.
