We study the dependence on the strength and orientation of applied uniaxial strain of the Drude weight in the conductivity of graphene.We find a non-monotonic dependence on strain, which may be related to the proximity to several strain-induced electronic topological transitions. Given the relation between the Drude weight and the long-wavelength plasmon frequency, such a strain dependence can be evidenced by infrared spectroscopy measurements.
