3D - natisnjeni kompozitni piezoupornostni merilniki

Hribar, Gašper (author), Slavič, Janko (mentor)

Tehnologija 3D-tiska je prinesla nove možnosti za izdelavo piezoupornostnih merilnih zaznaval. Tehnologija je relativno nova in je na področju električno prevodnih materialov pomanjkljivo raziskana. Zaključno delo obsega teoretično opredelitev piezoupornostnega učinka v različnih materialih, pri različnih vrstah obremenitve in mehanizme njegovega delovanja. V sklopu zaključnega dela je bilo predstavljeno 3D-tiskanje in procesni parametri, ki vplivajo na električno prevodnost polimernih kompozitov. Predstavljena je bila tudi razlika med statično in dinamično piezoupornostjo. Ob dinamični piezoupornosti kompozitov so bili predstavljeni uspešno izdelani koncepti 3D-natisnjenih pospeškomerov in njihove lastnosti.

• Title: 3D printed composite piezoresistive gauges

Abstract

3D printing technology has brought new options for production of piezoresistive gauges. The technology is relatively new and the research is limited when it comes to electrically conductive materials. The final thesis gives a theoretical definition of the phenomenon of piezoresistivity in different materials and under different types of loads. It also gives a theoretical overview of different mechanisms of piezoresistivity. As part of the final thesis, 3D printing and process parameters that affect the electrical conductivity of polymer composites have been presented. The difference between static and dynamic piezoresistivity has also been presented. Along with the dynamic piezoresistivity of composites, successfully developed concepts of 3D printed accelerometers and their properties have been presented.
