In this work, the elastic layered rubber-graphene composite based multi-functional sensor has been fabricated by rubbing-in technology. The effects of temperature, displacement, pressure and humidity on the impedance of the multi-functional sensor has been investigated in the frequency range of 0-200 kHz. The impedance of the samples decreased under the effect of uniaxial compressive displacement and under the effect of pressure. The temperature coefficient of the samples was found to be -0.836 and -0.862 %/°C with the increase in temperature from 29 °C to 54 °C, respectively, while the impedance of the samples decreased 1.26 ± 0.01 times with the increase in temperature from 29 °C to 54 °C while, respectively. The humidity dependent cross-sensitivity of the samples was investigated in the relative humidity range of (58-93) %RH and no effect of humidity on the performance of the sensor has been observed. The elastic layered rubber-graphene composite potentially can be used as displacement, frequency, temperature and pressure sensors.
在这项工作中，基于弹性层状橡胶-石墨烯复合材料的多功能传感器已通过研磨技术制备而成。在0-200kHz频率范围内，研究了温度、位移、压力和湿度对该多功能传感器阻抗的影响。在单轴压缩位移和压力作用下，样品的阻抗降低。当温度从29°C升高到54°C时，样品的温度系数分别为-0.836%/°C和-0.862%/°C，而当温度从29°C升高到54°C时，样品的阻抗分别降低了1.26±0.01倍。在相对湿度范围为(58-93)%RH内研究了样品的湿度相关交叉敏感性，未观察到湿度对传感器性能的影响。弹性层状橡胶-石墨烯复合材料有潜力用作位移、频率、温度和压力传感器。
