Abstract
Abstract 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 ~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 (~ 0.2 kPa −1 ), high cycle stability, and selective response to the applied pressure with a linear relationship of ~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.
