BPN772: Graphene for Room Temperature Gas Sensors


As air pollution from industrial and automobile emissions becomes more and more severe, a personalized, integrated, gas sensor is desirable for everyone to monitor everyday air quality, as well as their personal health condition noninvasively. Such sensors should have desirable features like energy efficiency, miniature size, accurate response (down to ppm level), and selectivity. Traditional bulk MOX-based gas sensors work in the temperature range of 300C to 400C, which requires large amounts of energy to power the heater. We propose using a graphene-based field effect transistor as a label-free sensor platform to detect gas selectively by measuring its electrical properties at room temperature.
