 This course introduces the concept and principles of compliant mechanisms and presents the design methods in detail. Various applications of compliant mechanisms in consumer products, microsystems, aerospace, automotive, and biomedical industries will be touched upon throughout the course. It is a comprehensive treatment of the growing field of compliant mechanisms starting from the classics and basics and ending with the state of the art.
