A model for integrating multiphysics couplings and consideration of manufacturability in the micro products design process.
Microproduct design is a multidisciplinary task which most of the time requires to couple several physical principles to obtain the right product behaviour. Various actors are involved throughout the product design process : physical principles and manufacturing processes experts for instance. Theses actors have to collaborate in accordance with integrated design principles in order to design highperformance products along its entire life cycle. Product-model concept has been developed for the design of macro products in order to enable the integration of the whole community of experts throughout the product lifecycle. Therefore assessing the relevance of this concept to the design of microproducts seems pertinent. To do so the limits of existing models are first highlighted, as well as the difficulty of applying them as a support for close collaboration between physical principal experts and the control of multiphysical coupling. Then the concepts required for the elaboration of a microproducts dedicated model are presented. The implemented model and its application onto the design of two microproducts (a MEMS switch RF and a microfluidic device) are finally presented and discussed.
