Graphene oxide is a carbonaceous material that has unique physicochemical properties (specific surface area, pollution resistance, conductivity, high mechanical strength) and can be produced in large quantities with relative ease. It is a material formed by the oxidation of graphene, which can be further modified with, for example, ascorbic acid to form reduced graphene oxide (rGO), or with hydrogen peroxide to form holey graphene oxide (HGO). The application of graphene oxide and its modifications in processes leads to improved sensitivity, electrocatalytic behavior and reduced fouling. Thus, a kampron, which is an electronic component with graphene oxide derivatives fabricated using 3D printing technology, has been experimentally prepared with the advantage of applications in various fields – physical, chemical and biological. Thus, in several stages, the action in the physical domain (pressure), chemical domain (gases and vapors) and biological domain (gases exhaled from the lungs) will be investigated. The changes caused by the investigated influences on the sensors are reflected by a change in the voltage on the sensor. This paper focuses on the first stage of the research, i.e. the fabrication and verification of reactivity of sensors printed in a single layer, which are similar to conventional comb or spiral sensors. The next stages of the research will focus on the investigation of sensors arranged in multiple layers, with the final stage involving the preparation of sensors with complex spatial shapes, while higher sensitivity is also expected. Carbon materials in the form of filaments will be used for 3D printing.
