Graphene, an electrically conductive reinforcement material, is investigated of its strain – sensing capabilities in the form of a thermoplastic polyurethane – graphene oxide (TPU-GO) composite. The results reveal that the TPU-GO strain sensor is better with the addition of the polyethylene glycol (PEG) (TPU-GO-PEG) that behaves as a binder and be further enhanced by forming a hybrid structure of silica (SiO2) (TPU-GO-SiO2) in the polymer matrix. It is further examined by its strain sensing performance in terms of stretch-release cycles at different strain, durability, and various strain speed. It is notable that the TPU-GO-SiO2 strain sensor obtained the highest gauge factor (GF= 28.7) and significantly enhanced mechanical properties, thermal stability, and electrical response and long-term durability (＞ 20,000 cycles).
