Electrospun ZnO/SiO₂ hybrid nanofibers for flexible pressure sensor

Abstract

method [4], thermal evaporation method [5] and sol-gel method [6]. However, the synthesized nanomaterials tend to aggregate in the fibrous structure in the high concentration solution, resulting in the most nanofibrous membranes are generally brittle [7]. It is known to us all that the flexible devices based on ZnO nanofibers, including lithium ion batteries, hydrogen sensors, and photocatalytic thin film reactors have significant applications [8], which is important for the future development of environmental remediation [9]. However, the potential applications of ZnO in optoelectronic devices are limited due to its brittleness. Therefore, it is challenging to improve the flexibility of ZnO. In general, ZnO can be considered as a candidate material for the preparation of

Fundamentals and Applications of ZnO-Nanowire-Based Piezotronics and Piezo-Phototronics

“…Moreover, the layered NW in the piezoelectric mode exhibited excellent mechanical durability under repeated compression cycles (>1000 cycles). In addition to the multilayer structure, textile fiber type devices, such as ZnO and SiO2 woven into mixed fibers, and flexible devices made into thin films show excellent sensitivity and durability [103].…”

Flexible Stannum-Doped SrTiO3 Nanofiber Membranes for Highly Sensitive and Reliable Piezoresistive Pressure Sensors

“…Compared with the aforementioned sensors, ceramic material-based piezoresistive sensors that have tolerance to a harsh environment, high sensitivity, fast response and recovery, and a wide working range are ideal candidates for monitoring pressures in the field such as fire-protecting and reaction vessels. − However, current ceramic materials are fragile with little resistance to deformation; thus, it is highly desired to design and construct flexible ceramic material-based piezoresitive sensors. An effective way to fabricate flexible ceramic materials is to construct fibrous structures with high aspect ratios .…”

Structural and optical characteristics determined by the sputtering deposition conditions of oxide thin films

“…They are intensely investigated due to their versatile properties, such as high transmission in the visible range [12,13] and broad energy bandgap [14][15][16], among others. Among the important applications of these oxides are materials with dielectric properties used in the fabrication of metasurface structures, transparent conductive oxides and buffer layers used in solar cells, and materials used in sensor technology [6,8,[17][18][19][20][21]. Materials with dielectric properties (e.g., SiO 2 and ZnO) exhibit a dependence of the electrical resistance with temperature [22,23].…”
