Today s electronic devices strive for new form factors - to make them foldable, stretchable, and deformable. To produce such devices that are highly stretchable or deformable, it is necessary to develop electrodes and circuit lines whose electrical properties can withstand harsh deformation or mechanical damage. To this, POSTECH-Yonsei University joint research team has recently developed liquid metal ink to accelerate printed electronic devices that can be changed into any shape.
