We systematically investigate the long-neglected low-temperature fusing behavior of silver micro/nanodendrites and demonstrate feasibility employing this intriguing property for printed electronics application, i.e., fuse-links. Fuse-links have experienced insignificant changes since they were invented in 1890s. By introducing micro/nanodendrites-based electrically conductive composites (ECCs) as a fusible element, coupled with state-of-the-art technology, key performance characteristics...
