Short summary
Nickel–Carbon thin films are excellent materials for strain and pressure sensors: they have a sensitivity much higher than conventional metal films and have tunable resistance–temperature characteristics. We investigate the electron conduction mechanisms that lead to their large sensitivity through modeling and numerical simulations. Transverse sensitivity is explained. It is shown in agreement with experiments that the largest sensitivity occurs for a specific nickel/carbon concentration.
