abstract = {In this paper, we present a simple and inexpensive method for the fabrication of
high-performance graphene-based heaters on different large-scale substrates through the laser
photothermal reduction of graphene oxide (laser-reduced graphene-oxide, LrGO). This method
allows an efficient and localized high level of reduction and therefore a good electrical conductivity
of the treated films. The performance of the heaters is studied in terms of steady-state temperature,
power consumption, and time response for different substrates and sizes. The results show that the
LrGO heaters can achieve stable steady-state temperatures higher than 200 ºC when a voltage of 15 V
is applied, featuring a time constant of around 4 s and a heat transfer coefficient of ~200 ºC cm2/W.
These characteristics are compared with other technologies in this field, demonstrating that the
fabrication approach described in this work is competitive and promising to fabricate large-scale
flexible heaters with a very fast response and high steady-state temperatures in a cost-effective way.
This technology can be easily combined with other fabrication methods, such as screen printing or
spray-deposition, for the manufacturing of complete sensing systems where the temperature control
is required to adjust functionalities or to tune sensitivity or selectivity.},
