Lamina emergent mechanisms (LEMs)
Encyclopedia
Lamina Emergent Mechanisms also known as LEMs are a subset of compliant mechanism
s fabricated from planar materials (lamina) and have motion emerging from the fabrication plane. LEMs use compliance, or the deflection of flexible members to achieve motion.

Compliant mechanism
In mechanical engineering, compliant mechanisms are flexible mechanisms that transfer an input force or displacement to another point through elastic body deformation...

Background
Ortho-Planar Mechanisms are an earlier concept similar to LEMs. More well known LEMs include pop-up bookPop-up book
The term pop-up book is often applied to any three-dimensional or movable book, although properly the umbrella term movable book covers pop-ups, transformations, tunnel books, volvelles, flaps, pull-tabs, pop-outs, pull-downs, and more, each of which performs in a different manner...

Deployable structure
A deployable structure is a structure that can change shape so as to significantly change its size.Examples of deployable structures are umbrellas, bistable structures, some tensegrity structures, bistable structures, some Origami shapes and scissor-like structures. Deployable structures are also...
