Integration of Piezoresistive Sensors into AM Structural Components: Evaluation of Sensor Properties and Its Impact on Component Mechanical Performance

Abstract

Abstract Additive manufacturing (AM) technology has experienced significant growth in recent years, opening new prospects across various sectors, from biomedicine to aerospace. Among these, the Fused Filament Fabrication (FFF) additive manufacturing technology, which deposits material layer by layer, enables the integration of piezoelectric material during the printing process, thereby allowing for the creation of sensors within thermoplastic components. Such sensors have the potential to monitor and detect various internal physical parameters within the component at locations inaccessible to traditional sensors. In this field, scientific research is continuously advancing, primarily aimed at developing sensors with high performance. In this context, the objective of this study is to assess the measurement properties, both static and dynamic, of sensors produced using this technology and to evaluate the influence on the static and dynamic behavior of the component caused by the incorporation of these sensors within the component itself.
