I will explain in examples how to incroporate the dependence on spin structure in fermionic lattice models. In two dimensions, I show to construct a spin-TQFT out of a superalgebra. In three dimensions, it turns out that fermionic lattice models are related to bosonic models with a global 1-form symmetry. This bosonization statement can be used to classify Symmetry Protected Topologicall phases of fermions.
