Fig. 1: Thin-film superconductor with bending-strain along a constant curve with arclength s (top), and (below) an SNS Josephson junction with uniformly curved superconductors and an uncurved normal metal.

Orthonormal, curvilinear unit vectors in the tangential \(\hat{{\mathcal{T}}}(s)\), normal \(\hat{{\mathcal{N}}}(s)\), and binormal \(\hat{{\mathcal{B}}}(s)\) direction, as well as the radius of curvature R, are indicated. In the inset, red represents tensile strain, and blue indicates compressive strain of the lattice.
