Lattice deformations act on the low-energy excitations of Dirac materials aseffective axial vector fields. This allows to directly detect quantum anomaliesof Dirac materials via the response to axial gauge fields. We investigate theparity anomaly in Dirac nodal line semimetals induced by lattice vibrations,and establish a topological piezoelectric effect; i.e., periodic latticedeformations generate topological Hall currents that are transverse to thedeformation field. The currents induced by this piezoelectric effect aredissipationless and their magnitude is completely determined by the length ofthe nodal ring, leading to a semi-quantized transport coefficient. Ourtheoretical proposal can be experimentally realized in various nodal linesemimetals, such as CaAgP and Ca$_{_3}$P${_2}$.
