Abstract: Components of the piezoelectric modulus tensor in graphene-like carbon 2D supracrystals with a periodic perforation breaking the centrosymmetry of the structure have been calculated. It has been shown that the piezoelectric moduli of the supracrystals with $sp^2$ hybridization are one order of magnitude lower and those of the supracrystals with $sp^3$ hybridization are several time higher than in lithium niobate.
