tIn this paper the use of multi-transduction principle for sensing materials development is reviewed. Inparticular, the application of porphyrin-based films to a multi-transduction Electronic Tongue systemfor different analytical tasks is presented. The optical response of sensing films was registered by meansof Computer Screen Photoassisted Technology (CSPT) that applies familiar devices, such as computermonitor screen and web-camera, as illumination light source and signal detectors. Simultaneously theelectrochemical amperometric or potentiometric response of the same sensing material was measured.Data analysis combining both signals significantly improves the performance of the Electronic Tongue,thus opening new frontiers in application of such a system.
