“We developed the new material using fluorographene chemistry by removing fluorine atoms and attaching benzylamine to the available reactive sites. This proved to be a crucial step in creating the temperature sensor. This technology allowed us to significantly minimize the adverse effects of humidity, typically the most challenging issue for such devices,” explained Petr Jakubec from CATRIN, a co-author of the study published in the prestigious journal Advanced Electronic Materials.
According to the authors, the new sensor offers significant advantages over traditional sensors, primarily due to its high accuracy. “It exhibits temperature resistivity that is twice as high as that of conventional platinum thermometers. A common issue with temperature sensors is their varying responses to changes in relative humidity. As a result, they often need to be wrapped in an insulating layer, which reduces their response rate. Our material, however, is stable and insensitive to humidity, allowing it to function in direct contact with the environment. This means it can measure temperature more accurately and quickly, better meeting the needs of modern industry,” stated the team leader Michal Otyepka from CATRIN and IT4Innovations VSB-TUO.
The sensor can be produced using inexpensive and rapid printing technologies, making it cost-effective to manufacture and easily scalable. This efficiency positions it as an ideal choice for widespread use in commercial applications.
Temperature monitoring and regulation are essential in various environments, including industrial, residential, and storage settings. Consequently, the demand for affordable, efficient, and durable temperature sensors is on the rise.
