“…In a memristor with a planar structure, the upper electrode layer and the lower electrode layer are on the same substrate plane, with a dielectric layer in the middle. Illarionov et al [97] deposited a layer of nano-gold on the substrate and used photolithography to etch a narrow bottleneck area in the middle of the electrode layer to form a trench across the electrode. Then they used inkjet printing to deposit titanium dioxide nanoparticles in the trench.…”

With the development of the Internet of things, artificial intelligence, and wearable devices, massive amounts of data are generated and need to be processed. High standards are required to store and analyze this information. In the face of the explosive growth of information, the memory used in data storage and processing faces great challenges. Among many types of memories, memristors have received extensive attentions due to their low energy consumption, strong tolerance, simple structure, and strong miniaturization. However, they still face many problems, especially in the application of artificial bionic synapses, which call for higher requirements in the mechanical properties of the device. The progress of integrated circuit and micro-processing manufacturing technology has greatly promoted development of the flexible memristor. The use of a flexible memristor to simulate nerve synapses will provide new methods for neural network computing and bionic sensing systems. In this paper, the materials and structure of the flexible memristor are summarized and discussed, and the latest configuration and new materials are described. In addition, this paper will focus on its application in artificial bionic synapses and discuss the challenges and development direction of flexible memristors from this perspective.

“…[77] reported inkjet printed memristor device based on ITO/GO/Ag structure, they diluted the graphene oxide (GO) ink in distilled water and ethanol to achieve low viscosity of 2.2 cp. Inkjet assisted memristor was fabricated by using TiO2 active layer and gold electrode [78]. They used a planar substrate coated with gold, a narrow trench (~700 nm) was developed with AFM and TiO2 ink was filled in the trench with inkjet printing to get a planar memristor as Gold/TiO2/Gold.…”

Memristor got the significant attraction to be the next generation memory device due to its small size, simple architecture, high density, and low power consumption. A memristor is a passive twoterminal primary electronic device with a built-in non-volatile memory function that can be fabricated in a crossbar structure. In the literature, independent studies have been reported on memristor manufacturing concerning the spatial resolution of the crossbar electrodes, and thickness of the active layer. However, this paper presents a comprehensive review different from others by comparing all the additive manufacturing technologies and their limitations for the development of a memristor array. A detailed study is performed about the pattern resolution, active layer fabrication, commonly used substrates, and device encapsulation methods. This review will provide a strong basis for the researchers, especially those working in the field of printed memristor devices.INDEX TERMS Memristor, printing technologies, thin films, crossbar electrodes, memristor fabrication.

“…The bio- and neurocompatibility of a TiO 2 film has been demonstrated in terms of its excellent adsorption of polylysine and primary neuronal cultures, high vitality, and electrophysiological activity (Roncador et al, 2017 ). Thus, TiO 2 can be implemented as a nanobiointerface coating and integrated with memristive electronics either as a planar configuration of memristors and electrodes (Illarionov et al, 2019 ) or as a functionalization of MEAs to provide good cell adhesion and signal transmission. The known examples are electrolyte/TiO 2 /Si( p -type) capacitors (Schoen and Fromherz, 2008 ) or capacitive TiO 2 /Al electrodes (Serb et al, 2020 ).…”

“…In addition, the early-stage processes such as nucleation, crystal growth, and aggregation (Teychené et al, 2020 ) may play a crucial role in the sol–gel synthesis of TiO 2 nanoparticles (Cheng et al, 2017 ). The memristive devices fabricated using the sol–gel method have various areas of application and operate at a threshold voltage ranging from ~0.5 V (Abunahla et al, 2018 ) to 1.5 V (Vilmi et al, 2016 ; Hu et al, 2020 ) or higher (Illarionov et al, 2019 ) with a resistive switching ratio R OFF / R ON of 10 1 -10 5 ( Table 1 ). Thus, the functional parameters of these devices may be variable with respect to the morphology and purity of the sol–gel product, deposition method (see section Fabrication), and annealing conditions (see section Annealing and Electric Properties).…”

Titanium dioxide (TiO 2 ) is one of the most widely used materials in resistive switching applications, including random-access memory, neuromorphic computing, biohybrid interfaces, and sensors. Most of these applications are still at an early stage of development and have technological challenges and a lack of fundamental comprehension. Furthermore, the functional memristive properties of TiO 2 thin films are heavily dependent on their processing methods, including the synthesis, fabrication, and post-fabrication treatment. Here, we outline and summarize the key milestone achievements, recent advances, and challenges related to the synthesis, technology, and applications of memristive TiO 2 . Following a brief introduction, we provide an overview of the major areas of application of TiO 2 -based memristive devices and discuss their synthesis, fabrication, and post-fabrication processing, as well as their functional properties.
