A two-dimensional resistivity mapping method is presented as an analysis tool for thin films. The spatial distribution of resistivity in the interior of the film is reconstructed with the data measured on its periphery. A square window with four electrodes on each side is fabricated as the test vehicle. While the current is applied to one electrode, the(More)
Carbon nanotube (CNT) is a promising candidate as a sensor material for the sensitive detection of gases/vapors, biomarkers, and even some radiation, as all these external variables affect the resistance and other properties of nanotubes, which forms the basis for sensing. Ultraviolet (UV) radiation does not impact the nanotube properties given the(More)
A carbon nanotube coated paper sensor has been developed for the detection of damages in structural components. Electrical resistance tomography is used to measure changes in electrical potential at various locations induced by applying a small electrical current to the sample. The spatial locations and magnitudes of multiple damages are predicted(More)
