Eduard Llobet (Barcelona, 1967) is a full professor at the Department of Electronic Engineering of the University of Tarragona (Spain). He was awarded a PhD in Telecom Eng in 1997 from the Technical University of Catalonia (Barcelona) and then joined the Gas Sensor Lab (UWarwick, UK) for a one-year postdoc. In 2006, he was an invited researcher at the CNRS-IMS in Bordeaux (France). From 2010 to 2014 he was Director of the Research Centre on Engineering of Materials and micro/nano Systems. He has co-authored some 160 papers at peer-reviewed journals, 8 book chapters and 5 patents. He belongs to the IEEE, RSC, ISOCS and the American Nano Society. In 2012 he received the RQR Award and in 2013 the ICREA Academia Award, both for quality in research.

He is currently addressing the fabrication of sensor arrays employing low-dimensional metal oxides and carbon nanomaterials. Cost-effective and industrially scalable methods are considered for bottom-up integration in MEMS or flexible platforms. The applications sought are (i) sensitive and selective gas microsensors for environmental monitoring, medicine or safety and (ii) heterogeneous catalysis.


Metal oxide nanowires integrated on silicon micromachined or flexible polymeric substrates for resistive or optical gas sensing

Metal oxides such as a ZnO, SnO2 or WO3 have been studied as gas sensitive materials for over 4 decades. Metal oxide gas sensors have nowadays an important share of the world gas sensor market, yet they still suffer from important drawbacks such as lack of selectivity and of stability. Here I will discuss on how low-dimensional, single crystalline, gas sensitive nanomaterials can be integrated onto silicon or polymeric substrates employing facile, bottom up approaches. Although the majority of the results shown will be for chemoresistors, preliminary results on optical gas detection will be presented as well. The gas sensing mechanisms will be discussed together with some strategies for the selective detection of species of interest.
