Lattice structure with piezoelectric behavior characterized in that the lattice structure () comprises a periodic succession of unitary cells (), wherein each unitary cell () is made of a dielectric material, is bending or torsion dominated and comprises nanometric structural connectors () connected to each other through nodes () defining a non-centrosymmetric shape having a topological constraint that induces torsion or bending of said structural connectors (); and wherein the unitary cells () are connected to each other at least in series defining a continuous electric potential accumulation path with two opposed ends (), the unitary cells () being arranged within the lattice structure () in a non-centrosymmetric disposition accumulating and conducting without cancellation the electric gradient generated on each unitary cell () through the lattice structure () to said two opposed ends ().
