Flexible protonic/electronic coupled neuron transistors self-assembled on paper substrates for logic applications

Flexible organic/inorganic hybrid and proton/electron coupled neuron transistors are self-assembled on paper substrates at room temperature. Solution-processed chitosan-based proton conductor gate dielectrics show a high electric-double-layer specific gate capacitance, which is favorable for low voltage portable application. High performance logic operations are realized on such flexible neuron transistors depending on the operation modes, i.e., OR logic for enhancement-mode device and AND logic for depletion-mode device. Proton/electron interfacial coupling in chitosan-gated neuron transistors is promising for the biological and sensing applications. (C) 2013 American Institute of Physics.
