Three-dimensional-printed complex mullite structures based on triply periodic minimal surfaces (TPMSs, namely, Schwartz and Gyroid) with two different thicknesses (Schwartz 1 Gyroid 1–4 mm, 2 2–6 mm) were fabricated tested as humidity sensors. The samples sintered at 1450 °C in the range from 0% to 89% relative (RH) room temperature evaluate effect of geometry thickness sensitivity. After water vapor exposure temperature, response was 2.84 under 89 RH% for structure (1.36 structure) 1.21 (7.00 structure). results showed that, RH, best sensors achieved structure. Sensors exhibit good repeatability, there no interference presence other gases.

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