Sensors


We have developed varied sensor technologies, operating via different transduction mechanisms (optical, luminescent, capacitive) and aimed at different targets. Specifically, we designed gas sensors, demonstrating high sensitivity and selectivity towards specific volatile organic compounds (VOCs) and organophosphates. Optical sensors for pollutants in water have been developed. Innovative strain sensors have been also fabricated through different chemical platforms.
