The advancement of integrated circuits has made it easier to reduce the size of increasingly potent wearable electronic devices. However, it is still difficult to seamlessly integrate electronic systems enabling unrestricted human behavior into wearable gadgets. The procedure of creating fiber devices by twisting fiber electrodes and incorporating them into textile systems is exhibited in recent work. These textile systems are highly resilient and flexible, which makes them ideal for various wearable applications, i.e., thread lithium-ion batteries (TLIBs), multi-ply sensing threads (MSTs), and thread electroluminescent devices (TELDs).
