“…The advantages of polyaniline memristive materials are connected to the low cost production, high flexibility, processability, and the possibility to create 3D stochastic memristive networks which can be successfully used in the learning process for a complex links pattern formation between input and output electrodes [21]. It also has been shown that the conductivity switching time of the polyaniline memristive device can be reduced by the proportional decreasing of the active PANI area under solid electrolyte [22]. The results of this work, along with the well-known ways to implement formal neurons based on CMOS technology [23,24], indicate the possibility of physical realization of complex ANN using a large number of organic memristive links.…”

materials makes the elements cheap and easy to manufacture. Moreover, organic materials allow simple chemical modification of the electrophysical properties and fabrication of flexible and stochastic 3D elements. [15-18] One of the first and most studied types of the organic memristive devices are polyaniline (PANI) based devices. [19-26] The structure and electrophysical properties of the PANI-based memristive devices are described elsewhere. [20] The main active component of the device is a thin PANI film connecting two metal electrodes. The third electrode is a silver wire separated from the film by a layer of solid electrolyte. The silver wire ("gate") is always connected to one of the substrate electrodes ("drain"), while the voltage is applied to the second one ("source"), as shown in Figure 1a. The RS is driven by a voltage-controlled electrochemical reaction at the PANI-electrolyte interface. The device switches to the low resistive state (LRS) under applied voltage exceeding the value of +0.4 V and to the high resistive state (HRS) under applied voltage less than +0.1 V. Its conductivity remains quite stable in the window between these values. Nonzero current at zero bias voltage is an essential and inevitable feature of all redox-based memristive devices. [27] The devices were shown to be stable for at least 10 4 switching cycles and able to hold each programmed resistive state for at least 10 3 s. [28,29] A detailed description of the switching mechanism is previously published. [21,22] During the RS, the insulating leucoemeraldine form of PANI transforms into the conductive emeraldine salt form and vice versa according to the following equation

“…[18,19] It has been shown that down-scaling of the devices' sizes results in the increase in the ON/OFF switching rate as well as endurance. [20,21] Despite this result, the obtained using a solid polymeric electrolyte can be considered as an important step forward for the use of OMD in complex circuits, it could be further improved by increasing the switching speed. In this work, we want to improve further these parameters using other types of electrolytes (ion motion in electrolyte is an important factor responsible for the speed of the device operation).…”

Being promising elements for neuromorphic computation, memristive devices have been often described as crucial elements for mimicking important synapse properties, such as memory and learning. Among them, organic memristive devices (OMDs) can claim low‐cost fabrication processes and the easy tunability of their electrical properties. Up to now, the major bottleneck for their larger uses in neuromorphic computation is low rate of the resistance switching and stability. Herein, a new approach is reported, based on the use of a liquid electrolyte, leading to the manufacturing of OMD with higher stability and faster resistive switching.
