Crack‐Controlled Stretchable Gold Conductive Electrode through One‐Step Carbon Nanotube Spray Deposition

Abstract Stretchable conductors are the key components of stretchable and wearable electronics systems. Although the micro‐structured cracking method is promising for realizing stretchable conductors, controlling the formation of cracks in stretchable conductors can be challenging. Simple control of...

description Abstract Stretchable conductors are the key components of stretchable and wearable electronics systems. Although the micro‐structured cracking method is promising for realizing stretchable conductors, controlling the formation of cracks in stretchable conductors can be challenging. Simple control of cracks is required for obtaining various high‐performance stretchable systems, including electrodes and interconnects. Here, a one‐step crack‐controlling method based on the simple and scalable spray‐based carbon nanotube deposition approach is reported. The crack‐controlled Au films exhibit high stretchability under up to 100% strain conditions, irrespective of the deposition conditions. The proposed one‐step crack‐control method is a universal technique for obtaining stretchable conductive materials.
