Flexible electrochemical sensors have gained huge attention over their significant properties and the probability of applying to any wearable electronic devices. LPG traces in definite concentrations leads to a fire accident, adverse health effects, and even causes death. The current study focuses on a flexible, room temperature LPG sensor based on Sm₂O₃/rGO hybrid nanocomposite with different loading factors (1, 3, and 5 wt%) coated on flexible polyethylene terephthalate (PET) substrate working electrodes. Eggshell membrane (ESM) template constituents are acts as a reducing agent during the hydrothermal synthesis of Sm₂O₃ nanorods. Flexible Sm₂O₃/rGO hybrid Chemiresistive gas sensor was tested for various gas sensing parameters. The decoration of Sm₂O₃ nanorods on 3 wt% rGO sheets exhibited good selectivity to liquefied petroleum gas (LPG) at room temperature gives a response of 116% at 700 ppm of LPG with a short response, recovery time and gained 99% response after bending with 94.5% stability of the sensor.

柔性电化学传感器因其重要的性能以及应用于任何可穿戴电子设备的可能性而受到了广泛的关注。一定浓度的LPG痕迹会导致火灾，对健康造成不利影响，甚至导致死亡。当前的研究集中在一种柔性室温LPG传感器上，该传感器基于Sm ₂ O ₃ / rGO杂化纳米复合材料，具有不同的负载系数（1、3和5 wt％），涂覆在柔性聚对苯二甲酸乙二醇酯（PET）基板工作电极上。蛋壳膜（ESM）模板成分在水热合成Sm ₂ O ₃纳米棒过程中充当还原剂。柔性Sm ₂ O ₃/ rGO混合型化学气体传感器经过各种气体传感参数测试。在3 wt％的rGO片材上装饰Sm ₂ O ₃纳米棒在室温下对液化石油气（LPG）表现出良好的选择性，在700 ppm LPG时响应为116％，响应时间短，恢复时间短，获得了99％的响应弯曲后具有94.5％的传感器稳定性。
