Abstract
Advancements in flexible electronics necessitate the development of corresponding testing apparatuses that can accommodate their unique deformation characteristics. Unlike traditional rigid electronics, flexible devices often experience complex, multi-directional deformations. This study focuses on the simultaneous application of bending and stretching deformations. We introduce an experimental apparatus that functions as an integrated component of a universal testing machine. It is designed to provide a uniform bending radius while allowing adjustable stretch induced strain for flexible electronic specimens. The apparatus is fabricated using 3D printing technology, enabling easy customization to accommodate various bending radii and dimensions specific to each specimen. Additionally, we analyzed the strain range for each design parameter to provide practical reference for future applications. To demonstrate the functionality of this experimental apparatus, we conduct tests on a flexible printed capacitor sensor, showcasing its effective performance under the specified deformations.
