Special Issue Information

Dear Colleagues,

Intelligent sensor technologies will revolutionize our everyday lives, providing safety, security, surveillance, monitoring, automation, and awareness in general. They drive innovation in many industrial applications and are vital for progress in medicine. Miniaturization through micro- and nanotechnology, novel materials and intelligent, networked, and integrated devices are key for future developments and improved performance. In addition, new engineering demands dictate a continuously improving characterization of the materials and components used in modern life. In all fields of science and engineering, standards of safety, productivity, and quality are rising. The absolute control which is necessary to raise these standards is achieved by means of sensors, which are the cornerstone in order to perform accurate characterization in any type of condition monitoring approach and any material field. The present Special Issue intends to explore new developments in sensors technology for nondestructive testing and modern applications in all domains of materials and processes. Topics include (but are not limited to):

  • Advancement in optical techniques (photoelasticity, interferometry, DIC, DVC, etc.);
  • Advances in sensor technology;
  • Biosensors;
  • Contactless ultrasonic sensors;
  • Elastic waves (ultrasonics, acoustic emission);
  • Electromagnetic antennas, radar, mmW;
  • Embedded sensors;
  • Energy harvesting for NDT;
  • Fiber sensors;
  • Infrared sensing;
  • Nanosensors;
  • Sensors for cultural heritage items;
  • Sensors for durability and durability of sensors.

In addition to developments in the sensor technology itself, the issue welcomes novel applications of sensors in materials and processes.

At low frequencies, in thin plates the phase velocity of the guided A0 mode can become slower than that of the ultrasound velocity in air. Such waves do not excite leaky waves in the surrounding air, and therefore, it is impossible to excite and receive them by conventional air-coupled methods. The objective of this research was the development of an air-coupled technique for the reception of slow A0 mode in thin plastic films. This study demonstrates the feasibility of picking up a subsonic A0 mode in plastic films by air-coupled ultrasonic arrays. The air-coupled reception was based on an evanescent wave in air accompanying the propagating A0 mode in a film. The efficiency of the reception was enhanced by using a virtual array which was arranged from the data collected by a single air-coupled receiver. The signals measured at the points corresponding to the positions of the phase-matched array were recorded and processed. The transmitting array excited not only the A0 mode in the film, but also a direct wave in air. This wave propagated at ultrasound velocity in air and was faster than the evanescent wave. For efficient reception of the A0 mode, the additional signal-processing procedure based on the application of the 2D Fourier transform in a spatial–temporal domain. The obtained results can be useful for the development of novel air-coupled ultrasonic non-destructive testing techniques. Full article
