“…The bonding of the glass frit for the newly developed half-bridge gauge does not differ from that used with conventional silicon strain gauges [7,26,27]. The bonding process was carried out in three main steps: screen printing of the glass paste, its thermal conditioning and actual bonding [26][27][28]. Thermal conditioning transforms the glass paste into a glass layer.…”

Half-bridge silicon strain gauges are widely used in the fabrication of diaphragm-type high-pressure sensors, but in some applications, they suffer from low output sensitivity because of mounting position constraints. Through a special design and fabrication approach, a new half-bridge silicon strain gauge comprising one arc gauge responding to tangential strain and another linear gauge measuring radial strain was developed using Silicon-on-Glass (SiOG) substrate technology. The tangential gauge consists of grid patterns, such as the reciprocating arc of silicon piezoresistors on a thin glass substrate. When two half-bridges are connected to form a full bridge with arc-shaped gauges that respond to tangential strain, they have the advantage of providing much higher output sensitivity than a conventional half-bridge. Pressure sensors tested under pressure ranging from 0 to 50 bar at five different temperatures indicate a linear output with a typical sensitivity of approximately 16 mV/V/bar, a maximum zero shift of 0.05% FS, and a span shift of 0.03% FS. The higher output level of pressure sensing gauges will provide greater signal strength, thus maintaining a better signal-to-noise ratio than conventional pressure sensors. The offset and span shift curves are quite linear across the operating temperature range, giving the end user the advantage of using very simple algorithms for temperature compensation of offset and span shift.

This study deals with the process of developing and optimizing the spray coating method for large-area deposition of carbon nanotubes. Carbon nanotubes have excellent electrical and thermal properties and strength, so they are used in various fields of application. However, existing deposition methods have limitations. In this study, the possibility of the spray coating method for large-area deposition of carbon nanotubes is presented, and additional conditions for this are introduced. A spray coating solution was prepared using dichlorobenzene as a solvent for 3 mg carbon nanotubes. By controlling the spray coating speed, the spray coating conditions were optimized by analyzing the surface shape, structure, and resistance of the deposited carbon nanotubes. As a result, we confirmed the possibility of depositing carbon nanotubes on a large area through the spray coating method, and it is expected to contribute to increasing the application possibilities in industrial and scientific fields.

Strain gauges and strain gauge transducers are important tools in the field of material resistance research to measure the stresses and strains in solids. These methods and devices have a wide range of applications, from construction to mechanical engineering, where the mechanical properties of materials need to be monitored and optimized. The use of nanomaterials in strain gauges allows for more sensitive and compact sensors. Nanotechnology makes it possible to create strain gauges with improved mechanical and electrical properties. At the same time, nanomaterials have unique properties that make them ideal for use in strain gauges. This paper considers different types of composites based on polymer matrices with additives of dispersed nanomaterials, which are designed for strain gauge tasks. Thermoplastics and elastomers can be used as polymer matrices. Dispersed fillers can be based on MXene and nanomaterials such as carbon nanotubes, graphene, metals, etc. Despite the obvious advantages of strain gauges based on conducting polymers modified with dispersed structures, there are problems in creating effective strain gauges with the ability to operate under large deformations with an improved sensitivity and accuracy of measurements in a wide range. This article also provides brief information on the technical evolution of strain gauges, from wire and foil to polymer nanocomposites. A modern classification of strain gauges is provided. The disadvantages and advantages of existing strain gauges are shown. The review contains information on commercial strain gauges. The mechanisms of electrical conductivity formation in polymer composites for strain gauges are described in detail. The areas of application of polymer nanocomposite strain gauges are also specified in detail. The purpose of this review study is to determine the prospects for the use of various nanomaterials as additives in polymers to create strain gauges. The review is aimed at a wide range of readers.
