Washington, Jan 22 (ANI): Scientists have developed a new design for stretchable and bendy electronics that can be wrapped around complex shapes, without a reduction in electronic function.

The electronics have been designed by Jizhou Song, a professor in the University of Miami College of Engineering and his collaborators Professor John Rogers, at the University of Illinois and Professor Yonggang Huang, at Northwestern University.

The new mechanical design strategy is based on semiconductor nanomaterials that can offer high stretchability (e.g., 140 percent) and large twistability such as corkscrew twists with tight.

Potential uses for the new design include electronic devices for eye cameras, smart surgical gloves, body parts, airplane wings, back planes for liquid crystal displays and biomedical devises.

“Our design is of great interest because the requirements for complex shapes that can function during stretching, compression, bending, twisting and other types of extreme mechanical deformation are impossible to satisfy with conventional technology,” said Song.

The secret of the design is in the silicon (Si) islands on which the active devices or circuits are fabricated.

The islands form a chemically bonded, pre-strained elastomeric substrate.

Releasing the pre-strain causes the metal interconnects of the circuits to buckle and form arc-shaped structures, which accommodate the deformation and make the semiconductor materials much more stretchable, without inducing significant changes in their electrical properties.

The design is called noncoplanar mesh design.

The study describes a design system that can be stretched or compressed to high levels of strain, in any direction or combination of directions, with electronic properties that are independent of such strain, even in extreme arrangements.

These types of systems might enable new applications not possible with current methods. (ANI)
