SBRI Challenge - Non Destructive Evaluation (NDE)

Develop an NDE technique with capacitive resitivity imaging (CRI) technology providing the capability to map variations of bulk low-frequency electrical properties within a structure and sensitive to any defects (e.g. cracks and fractures) or alterations (e.g. corrosion) affecting either electrical resistivity or dielectric properties of a material. Develop the NDE technique in the following areas of military exploitation: • In-situ evaluation of structural materials covered by sheathing, cladding, panelling, paint, tiles, flooring, insulating blankets, spray-on sealants or similar; • Detection and monitoring of moisture and/or increased salinity in structural or building materials; • D…
