Thin-film technologies have been the backbone of large-scale electronics for decades. The electrical performances of the devices result from the improvement of the architectural and material properties. In new systems-on-chip, these technologies are increasingly involved. In order to develop new objects, such as connected objects, the skills and know-how of engineers and researchers have evolved into new architectures and new materials with multidisciplinary applications. An effort must be made for training and more particularly for the acquisition of know-how. The paper deals with: -the evolution of thin film technologies through research activities, - the societal issues for applications including the development of connected objects, - the need of training in higher education. This training is provided in France through a national network that has oriented the practice towards future digital and connected society. This transfer of research activities to higher education is the main mission of the academic world.
