Products from all branches of the industry may be entered for this category. These products should use new or familiar materials and materials properties (e.g. conduction, illumination, energy storage, material saving, etc.) in an innovative way. Original products or prototypes and scale models are required for the judging. A complete material sample would also be desirable. It is also possible to register product concepts or ideas in this category. In this case, for the jury to make its decision a comprehensive description is necessary that precisely illustrates the properties and functions of the product. Of course, it is also possible to send in prototypes, multimedia presentations or presentation boards in order to further explain the product concept or idea.
