By the end of this course, students will have acquired the skills to analyse, understand and identify the design process environment for microengineering devices. The course includes concepts specific to design processes in microengineering, such as the specificities due to the size of devices and microfabrication tools.

Students will be trained to understand the customer's need, formalise the problem, establish the requirements and derive the primary specifications. They will also know how to build the functional and physical architectures, and, if necessary, simulate, predict and validate the behaviours and performances to analyse the safety of operation. The course is designed to integrate concrete cases, allowing students to build a reference base.

Prerequisites

Basic knowledge of design methodologies

Learning Objectives

• Know how to apply design methods (writing functional specifications, functional analysis, FMECA, FAST, APTE, V-Model) and how to choose the most suitable in a given design process.
• Integrate into the design the specificities of the physical phenomena of microengineering products by implementing, if necessary, on a multi-criterias and product management software. For this module, "Knowllence: Robust Engineering Suite - Medical Device Suite" is used. 
• Understand and consider microengineering interactions for the production and maintenance of prototypes or series products.
• At the end of the course, the student will be able to apply and critically examine design techniques in microengineering in order to produce solutions that take into account health and safety aspects while respecting environmental and economic constraints.
