We developed a resistive pressure sensor based on stand-alone film graphene incorporated natural rubber latex (NR/G) composite fabricated in a simple solution casting method. The graphene dispersion had multilayer properties and an average lateral size of similar to 60 nm successfully incorporated into the NR matrix to form bilayer graphene composite with the I-2D/I-G calculated ratio of 1.301. The pressure sensor shows high sensitivity (similar to 0.2 kPa(-1)), high cycle stability, and selective response to the applied pressure with a linear relationship of similar to 6.0 kPa. This work shows that graphene incorporated natural rubber latex pressure sensors with applicable potentials for smart wearable devices to allow pressure detection.
