Abstract
Bio-inspired technologies have been developed to mimic the physiology of mammal's senses, in order to design novel analytical systems. These biomimetic systems, well known as Electronic Tongues (ETs) and Electronic Noses (ENs), are currently developed in many research groups around de world. In this paper, we will discuss specifically the development of ETs and their recent impact in the most widespread applications areas such as food processing, pharmaceutical and environmental monitoring. On the one hand, the paper describes the importance of these systems in the process of identifying flavors artificially by the use of multi-arrays of sensors and data processing techniques. On the other hand, a review is included, related to recent ETs’ patents of the last two decades, in order to give to the reader an overview of the importance of this research line which involves areas of knowledge ranging from engineering to chemistry.
