In this work we present the study, development and characterization of a cylindrical focused ultrasonic sensor based on a piezoelectric polymeric material. For the design and implementation of the transducer, we carried out simulations using the commercial tool k-Wave and we used a construction method with great repeatability and low cost. For the characterization of the detection system (sensor + amplifier), we made electrical and acoustic measurements that allowed to determine its sensitivity and equivalent pressure noise. The results of this work show that the implemented sensor is suitable for optoacoustic tomography.Downloads
