20.500.12556/RUL-143650 Modeling of single-process 3D-printed piezoelectric sensors with resistive electrodes the low-pass filtering effect Three-dimensional printing by material extrusion enables the production of fully functional dynamic piezoelectric sensors in a single process. Because the complete product is finished without additional processes or assembly steps, single-process manufacturing opens up new possibilities in the field of smart dynamic structures. However, due to material limitations, the 3D-printed piezoelectric sensors contain electrodes with significantly higher electrical resistance than classical piezoelectric sensors. The continuous distribution of the capacitance of the piezoelectric layer and the resistance of the electrodes results in low-pass filtering of the collected charge. Consequently, the usable frequency range of 3D-printed piezoelectric sensors is limited not only by the structural properties but also by the electrical properties. This research introduces an analytical model for determining the usable frequency range of a 3D-printed piezoelectric sensor with resistive electrodes. The model was used to determine the low-pass cutoff frequency and thus the usable frequency range of the 3D-printed piezoelectric sensor. The low-pass electrical cutoff frequency of the 3D-printed piezoelectric sensor was also experimentally investigated and good agreement was found with the analytical model. Based on this research, it is possible to design the electrical and dynamic characteristics of 3D-printed piezoelectric sensors. This research opens new possibilities for the design of future intelligent dynamic systems 3D printed in a single process. low-pass filter electrode resistance piezoelectric sensors thermoplastic material extrusion 3D printing nizkopasovni filter upornost elektrod piezoelektrično zaznavala termoplastična ekstruzija materiala 3D tisk true false true Angleški jezik Slovenski jezik Članek v reviji 2023-01-05 11:07:41 2023-01-05 11:07:46 2025-04-30 10:40:27 0000-00-00 00:00:00 2022 0 0 16 str. iss. 1, art. 158 Vol. 15 Dec. 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 004.925.84:681.586:621.3 2073-4360 10.3390/polym15010158 136317699 Kosir,_Slavic-Modeling_of_single-process_3D-printed_piezoelectric_sensors_with_resistive_electrodes.pdf Kosir,_Slavic-Modeling_of_single-process_3D-printed_piezoelectric_sensors_with_resistive_electrodes.pdf 1 67603277D8E95F70C054E30F8547D460 3f0edb47bc1e60c378be53d9b581a8d4fb80c0b46bfde610a4873a62b7b567da 0f29ff64-8ce1-11ed-9c94-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=165488 https://www.mdpi.com/2073-4360/15/1/158 1 95cb2f53-8ce0-11ed-9c94-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=165487 Fakulteta za strojništvo 0 0 0
