This paper presents the results of investigating impedance frequency characteristics of sensing elements based on composite materials with varying content of carbon nanotubes (MWCNTs) and graphene. Five different substrate designs for sensing elements were analyzed to determine the optimal configuration in terms of noise immunity. The temperature characteristics of samples were studied in the range from -40°C to +40°C, as well as their behavior under high-voltage exposure. It was found that samples with 1% content of MWCNT/graphene mixture in a 70/30 ratio demonstrate the most stable characteristics in the studied temperature range and frequencies up to 50 kHz.
