Flavio M. Shimizu is a collaborative researcher at the Department of Applied Physics, “Gleb Wataghin” Institute of Physics, University of Campinas (UNICAMP), São Paulo State, Brazil. He received his degree in Physics (2005), M.Sc. (2008), and Ph.D. (2012) in Materials Science and Technology (POSMat) from Universidade Estadual Paulista (UNESP - Presidente Prudente, Brazil), and conducted his post-doctoral research at the São Carlos Institute of Physics, São Paulo University (IFSC/USP São Carlos, Brazil) from 2012 to 2017, and Cranfield University (2014, UK). His main research areas are microelectrodes and nanostructured films for applications in sensing and biosensing, electronic tongues, and information visualization techniques. Maria Luisa Braunger is a postdoctoral researcher at Faculty of Science and Technology, São Paulo State University (UNESP) and a collaborative researcher at the “Gleb Wataghin” Institute of Physics (IFGW), University of Campinas (UNICAMP), São Paulo State, Brazil. She received her degree in Physics (2008) and M.Sc. in Applied Physics (2011) from UNESP (Rio Claro-SP, Brazil) and Ph.D. in Materials Science and Technology (2015) from UNESP (Presidente Prudente-SP, Brazil) and Chemistry from Université de Pau et des Pays de l'Adour (UPPA, Pau - France). She was a postdoctoral researcher at IFGW-UNICAMP from 2015 to 2020 and a visiting scholar (2017-2018) at School of Engineering and Applied Science, University of Pennsylvania (Penn, PA-USA) working in the development of microfluidic devices and electronic tongues. Antonio Riul Jr is currently an Associate Professor at the Department of Applied Physics, “Gleb Wataghin” Institute of Physics, University of Campinas (UNICAMP), São Paulo State, Brazil. He researches Materials Science using nanostructured films from self-assembled materials for the nano-engineering of interfaces using tunable materials. He also works with impedance measurements in e-tongue devices, nowadays focusing on multifunctional coatings formed by self-healing and conductive nanocomposites.
