DC Electric Metamaterial Behaviour in Tuned Fused Deposition Modelling Prints

Sponsored by IEEE Sensors Council (https://ieee-sensors.org/) Title: DC Electric Metamaterial Behaviour in Tuned Fused Deposition Modelling Prints Author: Alexander Dijkshoorn, Thijs Hamstra, Remco Sanders, Stefano Stramigioli, Gijs Krijnen Affiliation: University of Twente, Netherlands Abstract: This paper shows the realization of electric metamaterials with Fused Deposition Modelling by tuning the nozzle temperature, bed temperature and extrusion width to achieve anisotropic electrical conduction. The temperatures influence the magnitude of the contact resistance between printed lines, whereas the extrusion width determines the number of contacts per unit length. Electric metamaterials are interesting for sensing, e.g. by concentrating the current to achieve highly sensitive spots. In this work such a concentrator is 3D-printed and its operation is demonstrated through IR thermography and voltage measurements, as well as supported by FEM simulations.
