Graphene is a 2D material with remarkable properties. The present study demonstrates the fabrication of a graphene-based sensor for measuring the temperature and humidity of a metal body. The graphene sensor was fabricated by depositing a thin film of graphene nanoparticles between silver electrodes (separated by ∼50 μm) on a glass substrate. The graphene thin film was characterized by XRD, Raman spectroscopy and UV-vis techniques. The capacitance and resistance for both the relative humidity (in the range of 0–100% RH) and temperature (in the range of 230–310 K) were measured using an LCR meter at 1 kHz in a controlled chamber. The graphene-based sensor expressed high sensitivity with fast response and recovery times for both humidity and temperature with long stability and low hysteresis curves. The sensor was also tested on a metal body, which expressed a good response time. Moreover, the measured data of capacitance and resistance was analyzed with classical and neutrosophic analysis as an application of modern material statistics. It was observed that neutrosophic analysis is more flexible for analyzing the capacitance and resistance of the fabricated sensor.

制造基于石墨烯的传感器，通过不精确的数据分析检测金属体的湿度和温度
石墨烯是一种具有卓越性能的二维材料。本研究展示了一种基于石墨烯的传感器的制造，用于测量金属体的温度和湿度。石墨烯传感器是通过在玻璃基板上的银电极（间隔约 50 μm）之间沉积石墨烯纳米颗粒薄膜来制造的。通过XRD、拉曼光谱和UV-vis技术对石墨烯薄膜进行了表征。相对湿度（在 0-100% RH 范围内）和温度（在 230-310 K 范围内）的电容和电阻在受控室中使用 1 kHz 的 LCR 计测量。基于石墨烯的传感器表现出高灵敏度，对湿度和温度具有快速响应和恢复时间，具有长稳定性和低滞后曲线。该传感器还在金属机身上进行了测试，这表示了良好的响应时间。此外，作为现代材料统计的应用，采用经典和中智分析对电容和电阻的测量数据进行了分析。据观察，中智分析对于分析制造的传感器的电容和电阻更为灵活。
