In the last years, the Joule effect in the sensing material, the so called self-heating effect, offered and alternative method to provide this energy: the probing current (or voltage) applied to measure the sensor signal also serves to heat up the sensor active film. Here, evidences of self-heating effects occurring on large arrays of nanostructures fabricated with low-cost methods are provided. The methodology is proven to be suitable to sense gases (humidity, NH3 and NO2) with low-powered heater-free devices.4 p.application/pdfengCC BY-NC-ND, (c) Monereo et al., 2015http://creativecommons.org/licenses/by-nc-nd/4.0/Detectors de gasosNanoestructuresGas detectorsNanostructuresA low-cost approach to low-power gas sensors based on self-heating effects in large arrays of nanostructuresinfo:eu-repo/semantics/conferenceObjectinfo:eu-repo/semantics/openAccess
