Abstract
Pametne strukture predstavljajo nov pristop k reševanju problemov. Združujejo zaznavala in aktuatorje v en sistem, ki spremlja stanje okolice in nanj ustrezno reagira. Stalni razvoj tehnologij 3D tiska omogoča izdelavo raznovrstnih struktur in odpira nova vrata na področju raziskovanja. Zaradi fleksibilnosti 3D tiska si v prihodnosti želimo z njim izdelovati pametne strukture. V zaključnem delu se ukvarjamo z zaznavalnim delom pametnih struktur, natančneje z enoprocesnim 3D tiskom pospeškomerov. Zasnovanih je bilo več različic pospeškomerov. Imajo obliko konzolno vpetega nosilca in delujejo na principu piezoupornosti. Skozi iteracijski postopek zasnove novih oblik pospeškomerov so bili proučeni različni vplivi na njihovo funkcionalnost. Poleg raziskanih vplivov je bil v okviru raziskave uspešno razvit in eksperimentalno preizkušen pospeškomer z relativno visoko občutljivostjo in širokim merilnim območjem. Predstavljen postopek zasnove in ostale ugotovitve zaključnega dela predstavljajo korak naprej na poti do izdelave in industrijske rabe enoprocesno 3D natisnjenih pametnih struktur.

Title:Design and experimental validation of a single process 3D printed accelerometer
Abstract:
Smart structures represent a new approach to solving problems. They combine sensors and actuators into one system that responds adaptively to environmental changes. The continuous development of 3D printing technologies enables us to produce different kinds of structures and creates new opportunities in the field of research. We would like to make smart structures using 3D printing technologies because of their flexibility. This thesis focuses on the sensory part of smart structures, specifically on single process 3D printing of accelerometers. Many versions of accelerometers were designed. They're based on a cantilever beam and work on the piezoresistive phenomenon. Throughout the iterative process of design, different effects on the accelerometer's function were identified and analyzed. Furthermore, an accelerometer with relatively high sensitivity and wide measurement range was designed and experimentally validated. The presented process of design and findings of the thesis represent a step forward towards the production and industrial use of a single process 3D printed smart structures.

Keywords:3D print, accelerometers, mechanical vibrations, modal analysis
