The demand for flexible and stretchable devices has been increasing in multiple fields, such as healthcare, energy harvesting, and artificial intelligence. In this study, we report a novel method to fabricate flexible and stretchable devices by integrating a kirigami sheet with an elastomer, both stretchable. Owing to the flatness of the kirigami sheet under no stress, electrodes can be patterned using a printing technique, which can enable large size and mass production. Kirigami sheets form three-dimensional shapes under stress/strain. The integration of kirigami and elastomers is carried out by placing a liquid elastomer on the three-dimensional structure. A biaxially stretchable light-emitting device was fabricated by patterning the electrode on a kirigami sheet and placing a light-emitting elastomer on top of it. This study reports the fabrication method, fabricated device on activation, and stretchability.
