Sensing motors and supercapacitors are pivotal in empowering smart systems, honing energy management, and facilitating the seamless integration of responsive electronics. Harnessing the electrochemistry of methylcellulose-polyaniline (MC/PANI) composites, this research delves into their potential applications as reactive current sensing supercapacitors with single connectivity. The electrochemical traits of pristine polyaniline (PANI) and MC/PANI composites were analyzed and assessed for their potential applications in sensors and energy storage devices. With a specific capacitance of 300Fg, the MC/PANI_B3 composite-based device retained 87.01 % capacitance after 2000 cycles. Besides, based on electrical energy as the sensing parameter, the composite exhibited augmented cathodic and anodic current sensitivity of 8.77 mJmA and -8.86 mJmA, respectively. The ameliorated supercapacitor and current sensing parameters of MC/PANI_B3 are ascribed to the percolation threshold content of the conducting phase, which is endowed with optimal hydrogen bond-mediated interactions with methylcellulose (MC), thus confers an expanded chain conformation.
传感电机和超级电容器在为智能系统提供动力、优化能源管理以及促进响应式电子设备的无缝集成方面起着关键作用。本研究利用甲基纤维素-聚苯胺（MC/PANI）复合材料的电化学特性，深入研究其作为具有单连通性的反应电流传感超级电容器的潜在应用。对原始聚苯胺（PANI）和 MC/PANI 复合材料的电化学特性进行了分析和评估，以探索它们在传感器和储能设备中的潜在应用。基于 MC/PANI_B3 复合材料的器件具有 300Fg 的比电容，经过 2000 次循环后仍保留 87.01%的电容。此外，基于电能作为传感参数，该复合材料的阴极和阳极电流灵敏度分别提高了 8.77 mJmA 和-8.86 mJmA。MC/PANI_B3 的超级电容器和电流传感参数得到改善，这归因于导电相的渗流阈值含量，它与甲基纤维素（MC）具有最佳的氢键介导相互作用，从而赋予了扩展的链构象。
