Respiratory signals are critical clinical diagnostic criteria for respiratory diseases and health conditions, and respiratory sensors play a crucial role in achieving the desired respiratory monitoring effect. High sensitivity to a single factor can improve the reliability of respiratory monitoring, and maintaining the hygiene of the sensors is also important for daily health monitoring. Herein, we propose a flexible Au-modified anatase titanium dioxide resistive respiratory sensor, which can be mechanically compliantly attached to curved surfaces for respiratory monitoring in different modalities (i.e., respiratory intensity, frequency, and rate). The uniform and preferentially oriented anatase titanium dioxide films gained by the polymerassisted deposition technique can be fabricated on flexible substrates through a liquid-assisted transferring process. The Au modification can enhance surface plasmon resonance to facilitate the photocatalytic activity of titanium dioxide, and the optimized distribution of Au on the surface of titanium dioxide film made the sensor have an excellent antibacterial effect. The uniquely designed encapsulation can effectively control the contact between the surface of titanium dioxide films and electrodes, allowing the flexible sensor to exhibit fast response time (0.71 s) and recovery time (1.06 s) to respiratory as well as insensitivity or low sensitivity to other factors (i.e., gas composition, humidity, temperature, stress, and strain). This work provided an effective strategy for flexible wearable respiratory sensors and has great potential in daily respiratory monitoring for health management and pandemic control.

“…Metal oxides have received considerable attention because of their potential applications in nuclear targets [41][42][43][44][45][46][47] , spintronic devices [22][23][24][48][49][50][51][52][53] , and self-cleaning glasses [54] due to their versatile properties, including ferroelectricity, ferromagnetism, piezoelectricity, semiconductivity, and superconductivity. Many simple oxides, such as Eu 2 O 3 [41][42][43][44] , ZnO [21][22][23][24] , TiO 2 [1,[54][55][56][57][58] , and VO 2 [59][60][61][62][63][64] have been prepared by using PAD. Polymers can prevent metal ions from engaging in unwanted chemical reactions; thus, the growth of complex metal-oxide films through PAD is controllable and reproducible.…”

Two-dimensional (2D) materials have attracted considerable attention because of their novel and tunable electronic, optical, ferromagnetic, and chemical properties. Compared to mechanical exfoliation and chemical vapor deposition, polymer-assisted deposition (PAD) is more suitable for mass production of 2D materials owing to its good reproducibility and reliability. In this review, we summarize the recent development of PAD on syntheses of 2D materials. First, we introduce principles and processing steps of PAD. Second, 2D materials, including graphene, MoS2, and MoS2/glassy-graphene heterostructures, are presented to illustrate the power of PAD and provide readers with the opportunity to assess the method. Last, we discuss the future prospects and challenges in this research field. This review provides a novel technique for preparing 2D layered materials and may inspire new applications of 2D layered materials.

“…25,26 However, the preparation of electronics-quality oxide films by chemical solution deposition is generally considered enormously challenging since control of stoichiometry and chemical reactivity of the metals in the functional films is not always straightforward in solution. To improve such difficulties in the sol-gel process, in this study, we employed a polymer-assisted solution (PAS) process that utilizes the inherent stability of metal-polymer complexes in solution [27][28][29][30][31][32] to grow a solid electrolyte film for ReRAM. The polymer sequesters the metal ions from undesired chemical reactions such as pre-formation of the metal oxide in the solution, assuring an even coating of metal ions over the entire film and thus a uniform metal oxide film after the polymer is decomposed at elevated temperature.…”

In this study, we present a polymer-assisted solution (PAS) process to prepare TiO 2 electrolyte layers for resistive-switching random access memory (ReRAM). The PAS process utilizes the stability of metal-polymer complexes in the coating solution to form uniform and dense films. In addition, the viscosity of the PAS coating solution can easily be adapted for any currently used coating technique. The electrochemical-metallization-based (ECM-based) ReRAM devices were prepared by spin-coating the PAS coating solution on an indium tin oxide (ITO) glass substrate that is used as the bottom electrode. Cu was deposited on the PAS-TiO 2 electrolyte as an electrochemically active metal electrode used as the top electrode. The ECM-based ReRAM with the PAS-TiO 2 electrolyte layer demonstrated bipolar resistive-switching behavior with a memory window wider than 13, cycle endurance over 500 cycles, and retention time longer than 10 4 s. Analysis of the conduction mechanism in high and low resistive states indicates that the resistive switching is attributed to the formation and rupture of Cu conducting filaments (CFs) in the PAS-TiO 2 electrolyte layer. New nonvolatile memory devices with various material characteristics based on ferroelectric polarization, magnetic polarization, and material phase change have been investigated to overcome the scalability issue of modern flash memory devices.1-3 However, recent research efforts have focused on resistive-switching random access memory (ReRAM), also known as conductive-bridge random access memory (CBRAM) or electrochemical-metallization-based (ECMbased) ReRAM, due to its outstanding advantages including a simple structure, low switching power consumption, fast switching speed, and capability of both unipolar and bipolar switching modes.4-6 ECMbased ReRAM consists of a solid electrolyte thin film in between two electrodes, an electrochemically active metal (EAM) electrode such as Ag or Cu and an electrochemically inert metal (EIM) electrode such as Pt, Au, or W. The EAM, biased with a sufficiently positive-polarity voltage with respect to the counter electrode (EIM), is electrochemically dissolved and migrates through the solid electrolyte toward the EIM electrode. Consequently, a conducting bridge forms between the two electrodes, which is also known as a conducting filament (CF). The resistive switching in the ECM-based ReRAM relies on the formation (SET) and rupture (RESET) of the CFs in the solid electrolyte, which depend on the polarity of the applied voltage. 7,8 Various solid electrolyte materials such as perovskites, chalcogenides and metal oxides have been explored for the fabrication of ReRAM.9-21 Most solid electrolyte films have been deposited using vacuum based processes such as thermal oxidation, atomic layer deposition, pulsed laser deposition, sputtering, and thermal evaporation. 15,19,[22][23][24] There are also other efforts devoted to growing metal oxide films as the solid electrolyte layers using chemical solution deposition such as sol-gel process. 25,26 H...
