Development of Stretchable Electronics Using Geometric Strategies and Applications

Abstract

Soft and stretchable electronics, equipped with diverse functional devices, have recently garnered attention owing to their versatility in applications such as stretchable displays, flexible batteries, and electronic skin (e-skin). A fundamental challenge in realizing stretch-able electronics lies in conferring the necessary flexibility to crucial electrical components such as electrodes and devices. However, the prevalent electronic materials, exhibit limited stretchability, presenting a significant obstacle to the advancement of soft and stretchable electronics. To overcome this challenge, various strategies rooted in geometrical engineering have been explored to enhance the adaptability of rigid materials. This study delves into the realm of geometrical engineering by, examining techniques such as serpentine pat-terns, kirigami-inspired designs, and island structures, with a keen focus on recent progress and future prospects.
