System level modelling of autonomous microsystem
Résumé
We propose a multidisciplinary approach for embedded autonomous microsystems design. Such devices are usually performed with batteries involving the introduction of cables and a limited lifetime. Our aim is to support the design of autonomous microsystems able to harvest the available energy in their environment. Microsystem design requires multidisciplinary skills to get efficient structures that are consistent with the specifications. However, few designers have the expertise in all the implicated engineering fields. Thereby, we propose a multidisciplinary approach beginning by a problem analysis through functional analysis tools. Then, we develop an approach to select the microsystem architecture regarding the energy harvesting issue. This block decomposition helps designer to get a system-level modelling of the microsystem. This global model is then improved with specific simulations and the multidisciplinary aspect of the design is taken into account by creating gateways between specialised software programs.
