AOARD Test Case- Low-temperature adhesive, Stretchable, and Deformable Circuit Board for Next-Generation Electronics

Abstract

Understanding and designing the mechanical properties of stretchable substrates (surface and interior) is also important. Through this research, we intend to develop the optimal ratio of ink in the form that can be directly printed on various stretchable substrates including fabric. The developed ink can solve the issues of existing studies such as peeling from the substrate (lack of adhesion), electrical and mechanical durability limitations, mass production, and economic feasibility. As a key component in electronics, intrinsically stretchable electrodes enable the fabrication of high-density devices, as well as applications such as sensors, antennas, heaters, and more. A printable, stretchable, conductive ink based on liquid metal nano--micro- particles, e.g., Ag flakes with plate-shapes, and their combination, will be used in this proposal. The mechanical and electrical properties of the ink depending on the composition and rheological control of the composite.
