In the contemporary age of sensing technologies for broad applications such as the Internet of Things, the capability to make low power, versatile, small form factor gas sensors could transform the fields of gas sensing systems into wearable/cellphone-based chemical interfaces for odor recognition, air quality, and personal health monitoring applications. Recent advances in graphene and its manufacturing processes have led to new opportunities to design room temperature ultra low power gas sensors, yet key issues such as poor selectivity and long recovery time still impede its practical application. The presentation will introduce methods of addressing these two critical challenges: achieving gas selectivity on the pristine graphene surface and boosting the recovery speed of graphene at room temperature. bsac.berkeley.edu/rsscast
