KeywordStrain sensors Layered structure Ti3C2Tx Multilayer graphene Linear response
AbstractStrain sensors featured with high sensitivities and large ranges of linear responses are currently under urgent needs. Herein, we present a spontaneously formed Ti3C2Tx/graphene/PDMS layered structure, which can be divided into two layers when being stretched: a Ti3C2Tx dominated brittle upper layer and a flexible graphene/PDMS composite bottom layer. The balance between the destruction and maintenance of the conductive pathways through the synergetic motion of the upper and bottom layers ensure a high and steady gauge factor of the senor in a wide strain range (e.g., gauge factors of 190.8 and 1148.2 in strain ranges of 0–52.6% and 52.6–74.1%, respectively). The Ti3C2Tx/graphene/PDMS layered structure based strain sensor is also featured with a low detection limit (~0.025%), a high linearity (R2 > 0.98), a high cycling stability (over 5000 cycles), and an accurate monitoring of full-range human motions. Different breathing patterns in yoga are distinguished to demonstrate the practicability of the sensor.
