Action Potential Monitoring Using Neuronanorobots: NeuroelectricNanosensors

Nuno R B Martins, Wolfram Erlhagen, Robert A. Freitas Jr


Neuronanorobotics, a key future medical technology that can enable the preservation of human brain information, requires appropriate nanosensors. Action potentials encode the most resource-intensive functional brain data. This paper presents a theoretical design for electrical nanosensors intended for use in neuronanorobots to provide non-destructive, in vivo, continuous, real-time, single-spike monitoring of action potentials initiated and processed within the ~86 x 109 neurons of the human brain as intermediated through the ~2.4×1014 human brain synapses. The proposed ~3375 nm3 FET-based neuroelectricnanosensors could detect action potentials with a temporal resolution of at least 0.1 ms, enough for waveform characterisation even at the highest human neuron firing rates of 800 Hz.
