This work demonstrates a cost-e ective manufacturing method of flexible and fully printed
microheaters, using carbon nanotubes (CNTs) as the heating element. Two di erent structures with
di erent number of CNT layers have been characterized in detail. The benchmarking has been carried
out in terms of maximum operating temperature, as well as nominal resistance and input power for
di erent applied voltages. Their performances have been compared with previous reports for similar
devices, fabricated with other technologies. The results have shown that the heaters presented can
achieve high temperatures in a small area at lower voltages and lower input power. In particular,
the fully printed heaters fabricated on a flexible substrate covering an area of 3.2 mm2 and operating
at 9.5 V exhibit a maximum temperature point above 70 C with a power consumption below 200mW.
Therefore, we have demonstrated that this technology paves the way for a cost-e ective large-scale
fabrication of flexible microheaters aimed to be integrated in flexible sensors.
