  Mechanical deformations of graphene induce a term in the Dirac Hamiltonian
which is reminiscent of an electromagnetic vector potential. Strain gradients
along particular lattice directions induce local pseudomagnetic fields and
substantial energy gaps as indeed observed experimentally. Expanding this
analogy, we propose to complement the pseudomagnetic field by a pseudoelectric
field, generated by a time dependent oscillating stress applied to a graphene
ribbon. The joint Hall-like response to these crossed fields results in a
strain-induced charge current along the ribbon. We analyze in detail a
particular experimental implementation in the (pseudo) quantum Hall regime with
weak intervalley scattering. This allows us to predict an (approximately)
quantized Hall current which is unaffected by screening due to diffusion
currents.
