“…The experimental details can be found in the ESI. † Here, we should point out that the specific features of this device can be summarized as follows: (i) the source, drain, and channel are made of common heavily-doped ITO film (i.e., a junctionless transistor) 19,20 and (ii) the different gates and channels are directly coupled in the transistor network through a common SA bio-electrolyte. In a neural system, once a nociceptor is activated, pain information is transduced into long-range electrical signals and propagated into the spinal cord dorsal horn, thalamus, and cerebral cortex, respectively.…”

“…As one knows, a biological synapse permits an electrical signal to pass from one neuron to the next, in which neurotransmitters play a key role in information transmission. In the biological system, excitatory postsynaptic currents (EPSCs) can be observed with the change of potential in the membrane, induced by the opening of ion channels. − A typical EPSC response induced by an applied gate voltage pulse ( V G = 1 V, V DS = 0.5 V, T d = 10 ms) is shown in Figure b . The EPSC is suddenly increased to a maximum value of ∼0.7 μA during the voltage pulse applied and is gradually reduced to the resting current after the spike.…”

Emulating the essential synaptic behaviors using single synaptic transistor has attracted extensive attention for building the brain-inspired neuromorphic systems. However, few reports on synaptic transistors fabricated by solution processes have been reported. In this article, the indium oxide synaptic transistors based on polyimide substrates were fabricated by a nontoxic waterinducement method at a low temperature, and lithium perchlorate (LiClO 4 ) was dissolved in polyethylene oxide as the gate electrolyte. For water-inducement process, comparable electrical properties of the synaptic transistors can be achieved by prolonging the annealing time rather than high-temperature annealing with a relatively short time. The effect of the annealing time on the electrical performance of the electrolyte-gated transistors annealed at various temperatures was investigated. It is found that the electrolyte-gated-synaptic transistor on polyimide substrate annealed at 200 °C exhibits high electrical performance and good mechanical stability. Due to the ion migration relaxation dynamics in the polymer electrolyte, various important synaptic behaviors such as the excitatory postsynaptic current, paired-pulse facilitation, high-pass filtering characteristics, and long-term memory performance were successfully mimicked. The electrolyte-gated synaptic transistors based on solution-processed In 2 O 3 exhibit great potential in neuromorphological applications.

“…Given the presence of polar groups and the absence of mobile hydroxide ions in the Cr‐CS dielectric thin film, the capacitance behavior mainly arises from dipolar relaxation . Therefore, the C of the Cr‐CS dielectric thin films was extracted from the C – V measurements at a relatively high frequency compared to that for pristine CS thin films used in previous studies . The ZnO TFTs did not show a clean saturation regime due to the increased carrier scattering due to the complex nanorod network path, large surface area, and grain boundaries at the nanorod junctions .…”

The hydrophilic character of chitosan (CS) limits its use as a gate dielectric material in thin‐film transistors (TFTs) based on aqueous solution‐processable semiconductor materials. In this study, this drawback is overcome through controlled crosslinking of CS and report, for the first time, its application to aqueous solution‐processable TFTs. In comparison to natural CS thin films, crosslinked chitosan (Cr‐CS) thin films are hydrophobic. The dielectric properties of Cr‐CS thin films are explored through fabrication of metal–insulator–metal devices on a flexible substrate. Compared to natural CS, the Cr‐CS dielectric thin films show enhanced environmental and water stabilities, with a high breakdown voltage (10 V) and low leakage current (0.02 nA). The compatibility of Cr‐CS dielectric thin films with aqueous solution‐processable semiconductors is demonstrated by growing ZnO nanorods via a hydrothermal method to fabricate flexible TFT devices. The ZnO nanorod‐based TFTs show a high field‐effect mobility (linear regime) of 10.48 cm2 V−1 s−1. Low temperature processing conditions (below 100 °C) and water as the solvent are utilized to ensure the process is environmental friendly to address the e‐waste problem.
