Harvard created a metamaterial that changes shape and size on command

Researchers at Harvard University have created a mechanical 3D material that can change its configuration on command from a control device. This opens up great opportunities for creating various structures and structures, the shape of which can be changed if necessary.

The options range from a stand that can support significant weight and large transformable buildings to nano-sized items.

The original modular block was created according to the principle of origami engineering. It is based on the origami method, where strips of paper are joined together to create complex multifaceted shapes. The metamaterial structure built by scientists consists of extruded cubes with 24 faces and 36 edges. Like traditional origami products, this device can take on a wide variety of configurations using remotely controlled pneumatic actuators.

As you know, origami engineering has already been embodied in folding solar panels for spacecraft, surgical instruments and flexible electronic components. The new technology has become the development of this topic, which will further lead to the creation of a new type of remote executive devices.

“We have developed a three-dimensional thin-walled structure that can be used to create foldable reprogrammable objects, ” said one of the project's leading experts, Johannes Overvelde. "Their shape, volume and rigidity can be remotely controlled to give them the look they want."
