Nano-assembled films for taste sensor application

An artificial taste sensor based on different types of ultra-thin films of conducting polymers (a special class of plastics that can conduct electricity) and their mixture with a lipid-like material has been able to mimic the human palate. In addition, this electronic tongue has been successfully employed in the analysis of tastants, suppression effects, and commercial beverages throughout AC measurements (impedance spectroscopy) in a relatively low-cost, simple, and efficient way.
