Abstract: A system and method for detecting damage to a structure is provided. The system includes a voltage source and at least one capacitor formed as a layer within the structure and responsive to the voltage source. The system also includes at least one sensor responsive to the capacitor to sense a voltage of the capacitor. A controller responsive to the sensor determines if damage to the structure has occurred based on the variance of the voltage of the capacitor from a known reference value. A method for sensing damage to a structure involves providing a plurality of capacitors and a controller, and coupling the capacitors to at least one surface of the structure. A voltage of the capacitors is sensed using the controller, and the controller calculates a change in the voltage of the capacitors. The method can include signaling a display system if a change in the voltage occurs.

Abstract: A mobile platform is provided which has at least one component having an array of distributed piezoelectric transmitters and an associated array of distributed receivers. The receivers are configured to receive ultrasonic transmissions from the transmitters. Data from the receivers is stored in memory and processed through an algebraic reconstruction tomography algorithm which forms an image of the defect within the component. An algorithm is used to determine the position and size of the defect.
