Stretchable Ultrasonic Linear Array Based On Laser Processing

Stretchable ultrasonic transducer arrays are capable of breaking through the limitations of rigid and flexible ultrasonic transducers for coupling interfaces, and can conform intimately to a variety of complex surfaces. However, structural design and fabrication processes are huge challenges in the development of stretchable ultrasonic transducer arrays. In this work, we proposed a stretchable ultrasonic linear array that was fabricated using rapid and convenient laser processing. The proposed single-layered and double-sided conductive stretchable electrode configuration eliminated the blockage of acoustic waves. The mechanical and acoustic properties of the linear array were demonstrated and the localization of the steel wire using the array was also performed.
