Lattice deformations couple to electrons in graphene by giving rise to an effective gauge field [1,2]. This unique feature leads to the possibility of modifying the electronic properties by applying strain to the lattice [3,4]. The main properties of the interaction between electrons and long wavelength lattice deformations will be reviewed.
