Abstract In the field of structural engineering, integration smart materials and health monitoring (SHM) has given rise to self-sensing (SSM), leading a paradigm shift in SHM. This paper focuses on interplay between capabilities piezoelectric properties lead zirconate titanate (PZT) barium (BT) aluminium components. Leveraging Friction Stir Processing (FSP), study explores synthesis performance SSMs with embedded particles, potentially transforming engineering. The highlights FSP as key methodology for incorporating particles into materials, showcasing its potential developing enhanced functionalities. A specific focus is placed integrating PZT BT AA2017-T451 parts using FSP, metallographic assessments mechanical property evaluations conducted analyse particle distribution concentration. shows how are incorporated create SSM that responds external stimuli. Under cyclic loading, exhibit linear load-electrical response correlation, sensibility increasing at lower frequencies. Metallographic analysis homogeneous distribution, while induces increased brittleness brittle fractures. Yield strength remains relatively stable, but ultimate decreases post-FSP. Hardness variations indicate weaker bonding particles. Eddy’scurrent testing aligns hardness profiles, sensorial characterization reveals non-linear frequency-sensibility relationship, SSMs’ suitability low-frequency applications, particularly embedment.
