2016-101 - Modular Piezoelectric Sensor Array with Co-Integrated Electronics

Description:
  • Ultrasound imaging
  • Medical imaging
  • Non-destructive testing

Abstract

USC researchers have developed a a modular piezoelectric sensor array with co-integrated electronics and beamforming channels. This technology mitigates the negative side effects of previous 2D ultrasound array implementations, allowing for improved trace widths, decreased parasitic capacitance, and uncompromised axial resolution.

Benefit

  • Improved large area 2D ultrasound array methodology
  • Solves former problems with trace width, parasitic capacitance, and axial resolution

Market Application

Large area 2D ultrasound arrays are commonly used in medical imaging and non-destructive testing. However, the high number of required interconnections between the piezo-electric array and the respective buffering/switching electronics poses a challenge, and current proposed solutions have limitations in trace widths, parasitic capacitance, and axial resolution. Addressing these issues presents a promising opportunity to improve ultrasound imaging systems.
