Analysis and Finite Element Modelling of Resizable Nanopores

The first analysis and finite element modelling of resizable nanopore actuation is presented. Resizable nanopores are single pores fabricated in an elastomeric membrane and reversibly actuated by stretching and relaxing the membrane on macroscopic scales. The modelling, which assumes linear elasticity, effectively simulates the macroscopic actuation properties of the structure supporting the membrane and the membrane itself to within ∼10 μm of the pore. Nanoscale analysis and modelling of cylindrical and conical pores do not closely reproduce experimental results, revealing the critical mechanical importance of near‐pore deformation sustained during the fabrication process.
