Design methodology for sustainable IoT devices

The exponential growth of devices using Internet of Things (IoT) estimates about 75 billion connected objects by 2025. This rapid increase implies economic, societal and environmental impacts linked to the massive use of critical materials. Scarcity, geopolitical risks related to sources of supply, ethical and ecological costs of certain solutions generate medium-term technological locks in order to design sustainable systems integrating IoT devices including the associated regulations (for example the new European RoHs and Conflict Minerals Directives) upstream of technological research. However, today there are no design tools to comprehensively address sustainable IoT solutions, which integrates globally the resources mobilized. In the context of emerging applications for health, transport, environment, the choices that will be made about the type of components used, the modes of energy, the way in which the data will be collected will be decisive in terms of impacts on resources and therefore on the sustainability of the chosen models

This thesis aims to develop a methodology to anticipate these impacts. It will focus on solutions developed in different laboratories in an interdisciplinary way. It will be based on: (1) reliable, transparent and recent data for designing the solutions, (2) the quantity of components that the solution solicits in the so-called "virtual space (edge internet, datacenter, etc.) in order to study the effects caused by the alternative solutions and the new uses of these objects.
