Another very interesting area of application for our high-resolution, sub-micrometre-sized heat flux sensors is the measurement of heat flux through individual molecules. Thanks to the ongoing miniaturisation of electronic components and the increasing use of electrically conductiven, organicn molecules raises new questions regarding the properties of these molecules. In this context, it is not only their electrical conductivity that is of great interest, but alsotheir thermal thermal conductivity, in order to enable targeted temperature management of electronic components to be possible. A European joint project involving partner groups from England, Finland, France and the Switzerland. The aim is to explore the possibility of optimised cooling for individual components of an integrated circuitstructureboard, including through the use of molecular films, be investigated, which opens up new possibilitiesifor energy-efficient operation of, for example, sensor systems ,.
