Abstract

The disclosure describes techniques and systems for detecting a crack or defect in a material. In some examples, a method for detecting a crack or defect in a material may include applying an electrical signal across an electrode pair electrically coupled to the material; determining a reactive parameter between the electrode pair; and determining whether the material includes a crack or other defect based on the reactive parameter. In some examples, the reactive parameter may include a capacitance, an electrical phase difference, or the like.
