Abstract:

Printing multifunctional material has the immense potential of addressing present needs within condition monitoring or structural health monitoring. As a matter of fact, enabling a new additive manufacturing paradigm allows to redefine what a sensor is, or what sensors should resemble. Therefore, the properties of printed components must be precisely tailored to meet exigences imposed by specified structure and target application. Unfortunately, the number of commercially available multifunctional ink is still limited to fulfill an increasing trend in the area of integrated smart sensor devices. Our current research thus investigates the in-house creation of adaptable piezoelectric and piezoresistive inks, together with their potential applications in condition monitoring, particularly for aeronautics as well as medical field. In this seminar, we take a focus on the 3D printing process and design optimizations of multifunctional inks that are supposed to be integrated into mechatronic devices.”
