N2 - Fast electrical impedance tomography (EIT) can localize and record neural activities of peripheral nerves in real time, but prior EIT systems do not support high enough frame rate (<500fps) to catch neural activities. Towards the real-time neural EIT, we propose a power- and hardware-efficient EIT system based on baseline-cancelling incremental zoom structure with 47μ W and 0.055mm2/ch, and a novel image update scheme, focused refresh, boosting the frame rate to 5.7kfps.
