The Internet of Things brings intelligence and connectivity within industrial tools. It gathers a real-time knowledge of the equipment parameters, which allows optimizing the processes by a better control and monitoring of the manufacturing conditions. The accumulation of data allows statistical processing by machine learning to improve the process and control in real time thanks to more connectivity and embedded intelligence. At the heart of data collection in the tools, many sensors are designed based on a common sensing element: the strain gauge. However, the operating conditions in the industrial environment are extremely severe; the major degradation stimulus is temperature, with values commonly exceeding 400 ° C, eliminating the use of gauges that are performed exclusively on plastic substrates. The aim of this thesis is to develop high temperature gauge sensors, leveraging additive techniques for both the fabrication and integration of gauges on topologically optimized test bodies.

CEA Tech's materials platform focuses on the shaping of advanced ceramics and offers R&D partnerships in additive manufacturing involving ceramics parts. The proposed thesis aims the increase of the knowledge and expertise needed to design and realize ceramic / metal devices. The chosen application is the remote control and the remote power transfer of a mechatronic system consisting of one or several sensors. The first phase of the thesis of a duration of 9 months will consist in a bibliography study and a dimensioning study in order to choose the best ceramic / metal couple with respect to the application case. The second phase of a duration of 9 months will consist in additive manufacturing and metallization of planar prototypes and will consist in mechanical, morphological and dielectric characterization. The third phase of a duration of 12 months will lead to additive manufacturing and metallization of the final 3D prototype. Eventually, the performance of the prototype will be evaluated though functional testing.
