A gas sensor with a field effect transistor (FET) structure using semiconductor SWCNT is also a promising future application. The CNT sensor made this way and the conductive CNT wire described above ...

Long-term instability, irreversibility, and limited selectivity are the main drawbacks of widespread practical implementation. Since the sensor response declines over time, a process that cannot be ...

Additionally, through Professor Lee Wi Hyeong's research team at Konkuk University, it was confirmed that CNT wires with oxygen functional groups also exhibited excellent gas sensor performance ...

Schematic diagram of the sensor based on the optical transmittance changes of the CNT-embedded Ecoflex thin film. (Image: KAIST) (click on image to enlarge) Conventional piezo-resistive strain sensors ...
