Title: The Most Critical Material Property for Durability in Flexible Electronics Under Repeated Mechanical Stress Introduction
Flexible electronics are revolutionizing industries from wearable health monitors to foldable displays and soft robotics. A defining challenge in this field is ensuring long-term durability when devices undergo repeated mechanical stresses such as bending, folding, and stretching. While many material properties contribute to performance, the most critical factor influencing durability in this context is fatigue resistance—specifically, the intrinsic ability of a material to withstand structural degradation under cyclic mechanical loading. Understanding fatigue resistance helps engineers select or design materials capable of maintaining electrical integrity and mechanical stability over thousands of deformation cycles. This article explores why fatigue resistance dominates as the key material property, key factors affecting it, and promising materials being developed for next-generation flexible electronics. ---
