▼ [9p-W242-3] Complementary Skin Gas Sensor Based on Hybrid Structure using WO3 nanoparticles and Zeolites
キーワード：Gas sensor, Skin gas, Oxide semiconductor
Metal oxide semiconductor based gas sensors are widely used for health care gas sensors, detecting the respiratory and skin gases from human body and it makes health care and disease screening possible. Concentration of acetone skin gas is the index of metabolic data such as fat-burning in human body. By using the biological mechanism, it is possible to take health care analysis in home with mobile device.
Despite of wide use of WO3 semiconductor for gas sensor, lots of researches are still in progress to improve its gas selectivity.[1] Considering that porous zeolites show the various gas absorption characteristics by different pore sizes. By applying porous zeolites have different pore sizes on the gas sensors, it is expected to get high selectivity by adsorbing targeted gases onto zeolites. In addition that, combination with many kinds of gas sensors which have different gas sensitivity shows much better performance of sensors by signal analysis of each sensor.
