Reduced graphene oxide as ultra fast temperature sensor
  We demonstrate the excellent temperature sensing property of a chemically synthesized reduced graphene oxide (rGO). It is found that with increase in temperature from 80 to 375K, the resistivity of reduced graphene oxide monotonically decreases. The ultra-fast temperature sensing property is demonstrated by keeping and removing a block of ice under the rGO sensor, which shows the resistance of rGO increases by 15% in 592 miliseconds and recovers in 8.92 seconds. The temperature sensing of rGO is compared with a standard platinum thermo sensor (Pt 111) and found the sensitivity is much better in rGO.
