Short summary
This research is about future sensor devices for force, pressure, and weight. The core of such sensors for mechanical quantities is a thin film that reacts to deformation. We are developing new sensor films with higher output. Different compositions of metal containing carbon films are examined. Most preferable and stable films contain nickel and carbon. The microscopic film morphology is uncovered. Electron tunneling between nanoparticles is responsible for the very sensitive reaction.
