Resumen
In this work a 2-MHz flexible transducer probe more compact and capable of being attached directly over the surface was developed. An extra curvature sensor based on strain gauge construction embedded in the same flexible polymer matrix of the transducer was developed. This sensor is used to measure the curvature of the unknown non-planar surface in an attempt to determine the correct position of the emitter/receiver ceramics during scanning, in order to give a focal delay time law. This avoids problems related to beam distortions, enhancing the sensitivity of the transducer.
