Engineers invent a process to ‘dope’ carbon filaments with an additive to improve their electronic performance, paving the way for digital devices that bend.
Engineers would love to create flexible electronic devices, such as e-readers that could be folded to fit into a pocket. One approach they are trying involves designing circuits based on electronic fibers, known as carbon nanotubes (CNTs), instead of rigid silicon chips.
But reliability is essential. Most silicon chips are based on a
