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.
