The paper presents results of investigations of basic material properties of novel composites based on silicone resin and carbon nanotubes as a filler. The motivation for the research is a need for materials which provide better mechanical properties than standard wet Ag/AgCl electrodes. However, a critical issue is also obtaining defined electrical characteristics in order to preserve an ability to effectively record biomedical signals such as electrocardiography (ECG). Within the introduction chapter, related researches and the current state-of-the-art in the context of dry electrodes technology were described. In the next step technological aspects of components processing and forming as well as the morphology of substrates used in the research were presented. Thermally-cured silicone resin was utilized to obtain elastic properties of the resulting material. The carbon nanotubes (CNT) were chosen as a conductive medium which provides defined electrical impedance. A developed technological process allowed to deliver samples of reproducible structure and properties. In the next chapter, methods and results of conducted experiments involving electrical, mechanical and thermal examination were presented. Finally, achieved outcomes are promising in the context of improvements of the designed composite. Especially the conductivity below 100 Ohms constitutes a significant motivation for further research in the field of dry electrodes for biosignals acquisition.
