Graphene learns new “professions”


New properties of graphene

Graphene continues to amaze scientists with new opportunities. Origami and kirigami – this is the Japanese art of carving fancy paper figures. Scientists at Cornell University in New York decided to apply it to graphene sheets. As a result, flexible and expandable electronic components have appeared.

Some of the mechanical properties of graphene scientists at first imitated on a sheet of plain paper. To create graphene structures, they used micromanipulators – special needles with remote control.

According to one of the leading researchers of Professor Paul McEwen, the stretching of paper was almost identical to the graphene leaf. The Kirigami technique in this case can be used to create miniature moving graphene electrodes, springs and loops.

Unlike metal parts that lose their properties under significant bends, the graphene ones are very reliable. Any deformations, including tens of hundreds of times, practically do not affect the quality of work of such electronic devices.

One of the promising directions of using flexible electronics can be the creation of wearable devices for studying the activity of nerve cells and miniature robots. Professor of the Department of Solid Materials and Building Mechanics of the University of Trento Nicola Puño proposed to create a scale based on a spring of graphene:

“To measure the mass of the body, it is necessary to attach it to the spring and measure the elongation formed. Knowing the rigidity of the spring, you can easily calculate its weight. “
