The IR transparency of graphene is exploited for the first time for use in pyroelectric IR detection. Graphene's unique combination of IR transparency and electrical conductivity enables considerable improvement in the operating frequency of pyroelectric sensors, without degradation in detector sensitivity. This study presents a new perspective for using graphene in IR sensing and thermal imaging applications.
