To create functional sensor systems, we need materials with three distinct properties: a structural material, a sensoric material and a conductive material. The structural material is a non-conductive polymer which provides rigidity, stiffness and solidity to sensor system. The sensoric material is usually based on carbon in forms of graphene, soot or carbon nano-tubes. The conductive material is often the biggest challenge. When transmitting the signal, its resistance can cause noise, delay or overheating of elements which can result in large measurement errors or system failure. The thesis will focus on highly conductive polymer
composite filaments for 3D printing which are based on polymer matrix with metal particles. The mechanical properties of such composites and mechanisms that affect the establishment of a geometric and conductive mesh will be defined.
Results in the experimental part of this thesis will confirm that it is possible to add metal particles to a polymer material in order to form a conductive mesh without losing the favorable mechanical properties of the polymer.
