Medical Technology Warns of Structural Deficiencies

A common, non-invasive medical imaging technique used on human patients since the 1980s may prove useful for monitoring building and bridge health. A team from the University of Delaware is applying electrical impedance tomography (EIT) to create a conductivity image, or map, of the structure in question. The technique, which takes advantage of carbon-nanotube-based sensors, detects damage early on, is relatively inexpensive, and can be scaled up from the experiments currently under test.
