Context : Micro Electro Mechanical Systems (MEMS) are devices that combine mechanical, optical, or electromagnetic elements with electronics. They serve as sensors and/or actuators capable of interacting with their environment. These devices are ubiquitous in many modern applications, ranging from automotive sensors to implantable medical devices.[...]Various works have been conducted at FEMTO-ST in the field of micro-machining. In particular, the fabrication of molds using cleanroom technologies for micro-injection of polymers has been developed [2]. This manufacturing process could be an option for replacing silicon parts. The mold can also be produced using various technologies available at the MIFHySTO platform. Among these, wire electro-discharge machining allows for the creation of micrometer-scale patterns in ceramic materials [3].

PhD objective: The objective of the thesis is the development of hybrid micro-manufacturing processes for the fabrication of autonomous sensor components for structural health monitoring. Environmental analysis will be fully integrated into the process development approach. It will be based on the creation or selection of relevant environmental criteria to optimize from an environmental perspective. The proposed thesis work complements the activities of the European project FEDER-FSE+ SAMI in collaboration with the University of Franche-Comté, SUPMICROTECH ENSMM, and the companies SilMach and Axon’ Nanotec. It also lays the foundation for the directions defined in the MICRO team's project.

Applicant Profile :The candidate must hold a Master's degree or equivalent in the field of materials mechanics and machining processes. Knowledge in the field of life cycle analysis will be a plus. Only candidates with excellent grades in their Bachelor's and Master's degrees will be considered. Detail-oriented, motivated, and environmentally conscious, the candidate should have a profile indicating skills in mechanical design, as well as a strong preference for experimental characterization and microfabrication.
