This work presents the development and experimental validation of an ultrasound piezoelectric sensor for thermoacoustic imaging that exploits printed circuit boards technology to define with high precision the sensor active area while minimizing manufacturing complexity and cost. A prototype single-channel sensor with 4x4 mm active area has been manufactured and experimentally validated in electrical and acoustic testbenches.

Abstract
This work presents the development and experimental validation of an ultrasound piezoelectric sensor for thermoacoustic imaging that exploits printed circuit boards technology to define with high precision the sensor active area while minimizing manufacturing complexity and cost. A prototype single-channel sensor with 4x4 mm active area has been manufactured and experimentally validated in electrical and acoustic testbenches.
