Origami engineering could enable a rich design and manufacturing framework to build micro- to meter scale folding structures. At the micro-scale, several self-folding approaches have been recently studied, usually employing a simple bi-morph approach with differential strains applied across a flat sheet to cause local folding or creasing.  The strains can result from shape memory materials (thermal heat/magnetic), residual stresses (heat) or hydrogel swelling (water, PH, etc..).

We are interested in origami-engineering for designing multi-stable actuators, and demonstrate their application in applications ranging from micro-sensors and actuators, to macro-sclae structural materials ad robotics.
