  • Abstract : Measuring strains induced by loads on structural elements is a key component of structural health monitoring $(\text{SHM})$. Current methods are mostly based on localized measurements and offer limited information on distributed strain. We present results on distributed strain monitoring based on electrical impedance tomography $(\text{EIT})$ imaging of a painted, elastic surface coating. The method can extract information on the surface strain field by solving the EIT inverse problem based on measured data.
