An Introduction to Multilayer Lamina Emergent Mechanisms

Multiple-layer lamina emergent mechanisms (MLEMs) are the mechanisms made from multiple sheets (lamina) of material with motion that emerges out of the fabrication plane. Understanding how layers are used in existing products and in nature provides insight into how MLEMs can also use layers to achieve certain tasks. The multilayered nature of MLEMs and the interactions between these layers show how the capabilities of MLEMs are enhanced and allow them to meet specific design objectives. Layer separation is one objective for which MLEMs are well-suited. Layer separation can have a variety of applications and there are a number of different ways to design a MLEM to achieve this objective. [DOI: 10.1115/1.4004542]
