Intelligent functionalities coupled textiles have received massive attention in the wearable health monitoring devices owing to their lightweight, ease of wearability, intrinsic flexibility, and comfortable texture. This article describes multifunctional, highly conductive, wash durable, and re‐usable reduced graphene oxide (RGO) coated polyester knitted textiles by a simple, cost effective, and scalable dip‐dry‐reduce approach and a novel approach to integrate as fabricated RGO coated polyester knitted textile (RGT) with the wearable elastic band for electro/physiological signal monitoring. The RGT exhibits high conductivity of 0.23 KΩ sq −1 and excellent wash durability. The RGT textile as a strain sensor shows a high sensitivity of 4.1 and 8 at a strain of 5% along the course and wale direction, respectively, stability and durability for more than 1500 cycles and also shows its excellent performance in human motion detection. Obtained electrophysiological signals from the RGT electrodes integrated wearable elastic band are comparable to those of the conventional Ag/AgCl electrodes. Owing to its comfortable texture, ease of wearability, stability, and wash durability, the RGT has potential applications in the future wearable electronic devices.
