摘要
Abstract Recently, the demand for superior wearable strain sensors has been growing steadily with the widespread application of stretchable electronics. Based on polydimethylsiloxane (PDMS) and poly(3,4-ethylenedioxythiophene) (PEDOT):polystyrene sulfonate, it has good compatibility with graphene doping. Herein, an uncomplicated and capable pressure sensor based on PEDOT/PDMS-wrapped free-standing reduced graphene oxide (rGO) was devised and manufactured. The graphene-containing composite conductor exhibits superb electrical conductivity, resilience, and piezoresistive effect, and surprisingly exhibits excellent antibacterial capabilities and cycling constancy. The fast response and recovery times of this pressure sensor are below 9 and 21 ms, respectively. The magnitude of current changes did not fluctuate significantly after 10 000 cycles of use, which indicates the great dependence of the sensor. Strain sensors as one of primary demand is that composite conductors are attached straight to the mortal skin (joints, elbows and knees) for actual-time monitoring.
