Using inverse problem analysis, we designed a soft areal tactile sensor with pressure-sensitive conductive rubber that does not need complex central wiring because we estimate conductivity change, i.e., pressure on the sensor, in the center based on electrical impedance tomography (EIT), i.e., a type of inverse problem analysis. We discuss results demonstrating the sensor’s effectiveness.
