Benefits of technology

The new technology described by this patented allows for better testing of objects that are difficult or impossible to reach due to their complexity. It also makes it easier to detect complicated layers without relying solely upon sonar techniques like scans. This results in more efficient and effective analysis compared to previous methods such as manual probes.

Problems solved by technology

This patented technical problem addressed by this patents relates to detecting objects' interfaces or interior flaws during manufacturing processes due to their complexity and size limitations. Ultrasound tests have been developed but they require specialized equipment and trained operators, which makes it difficult to use these techniques outside laboratories. Additionally, existing solutions like spiral testers may also cause damage when trying to connect tubes together.

Abstract

The invention provides a stretchable ultrasonic transducer array which comprises a detecting array, a signal interface and a covering layer. The detecting array is provided with a plurality of transducers arranged according to the preset array shape, and the transducers are connected through an upper layer and a lower layer of stretchable wires. The signal interface is used for being connected with the detecting array and providing a signal output interface. The covering layer is formed by covering the detecting array with an elastic material. Compared with an existing traditional hard probe, the coupling mode of the stretchable ultrasonic transducer array and a tested object has essential progress, and the detecting effect and efficiency are greatly improved. Meanwhile, by means of the stretchable property, the stretchable ultrasonic transducer array can be dynamically attached to the tested object (including a developable surface and a non-developable surface) in any shape, the range of detected objects is widened, and therefore the stretchable ultrasonic transducer array can be applied to debonding detection of complex stratified structures and stress detection of complex structures.
