EIT creates a two-dimensional (2D) spatial map of conductivity by measuring the voltage of an array of electrodes placed at the boundary of a piezoresistive film. This piezoresistive film was made from multiwalled carbon nanotubes mixed with latex, which was deposited on the surface of the slabs through spray coating. The relative thinness of the piezoresistive film does not appreciably interfere with the mechanical response of the slabs. Along the periphery of the piezoresistive film, 12 equidistant electrodes were attached. At each electrode, direct current was applied while the voltage was being measured. The voltage measurements, using Newton’s one-step error reconstruction algorithm, produced a 2D map of conductivity. The 2D map of conductivity is directly proportional to the strain due to a piezoresistive film. Detailed procedures are explained in a previous study (38).
