20.500.12556/RUL-132234 Dynamic measurements using FDM 3D-printed embedded strain sensors 3D-printing technology is opening up new possibilities for the co-printing of sensory elements. While quasi-static research has shown promise, the dynamic performance has yet to be researched. This study researched smart 3D structures with embedded and printed sensory elements. The embedded strain sensor was based on the conductive PLA (Polylactic Acid) material. The research was focused on dynamic measurements of the strain and considered the theoretical background of the piezoresistivity of conductive PLA materials, the temperature effects, the nonlinearities, the dynamic range, the electromagnetic sensitivity and the frequency range. A quasi-static calibration used in the dynamic measurements was proposed. It was shown that the temperature effects were negligible, the sensory element was linear as long as the structure had a linear response, the dynamic range started at ∼ 30 μϵ and broadband performance was in the range of few kHz (depending on the size of the printed sensor). The promising results support future applications of smart 3D-printed systems with embedded sensory elements being used for dynamic measurements in areas where currently piezo-crystal-based sensors are used. 3D-printing strain sensors embedded sensors dynamic measurements fused deposition modeling smart structures 3D-tiskanje zaznavala deformacij vgrajeni senzorji dinamične meritve pametne strukture true false true Angleški jezik Slovenski jezik Članek v reviji 2021-10-18 14:51:50 2021-10-18 14:51:54 2022-09-12 04:11:33 0000-00-00 00:00:00 2019 0 0 15 str. iss. 12, art. 2661 Vol. 19 2019 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 531.3(045) 1424-8220 10.3390/s19122661 16662555 RAZ_Maurizi_Marco_2019.pdf RAZ_Maurizi_Marco_2019.pdf 1 471114215E3F9F96A33BA480DC1FE3FF 0d6b36987c6b8e0b077f928feb3919a6fbea9d6ea445b50b4ce4c5ff00d2dd31 5e34c700-3012-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=149796 https://www.mdpi.com/1424-8220/19/12/2661 1 29a00abf-3012-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=149795 Fakulteta za strojništvo Zdravstvena fakulteta 0 0 0
