Outperforming piezoelectric ultrasonics with high-reliability single-membrane cmut array elements

HIGHLIGHTS

  • who: Eric B. Dew from the (UNIVERSITY) have published the Article: Outperforming piezoelectric ultrasonics with high-reliability single-membrane CMUT array elements, in the Journal: (JOURNAL)
  • what: The authors designed CMUT array elements composed of a single long rectangular membrane with the aim of improving the output pressure and electromechanical efficiency. The authors compare the performance of three different modifications of this architecture: traditional contiguous dielectric isolated isolation post (IIP) and insulated electrode-post (EP) CMUTs. This work has included research into film quality14, surface roughness, and deposition recipes to mitigate charging15. While this approach . . .
