Abstract
The main focus of this thesis is the development and use of piezoelectric ceramic-polymer composites, for biomedical applications. The properties of piezoelectric materials such as barium titanate, barium calcium zirconate titanate, and potassium sodium niobate are explored, by examining their integration into printed polymer-based systems and their implications for use in medical devices and sensors.The thesis places considerable emphasis on the examination of these materials and their potential applications in wearable piezoelectric sensing systems. It examines the difficulties and factors to be taken into account while producing these materials, and explores the progression from conducting research to building wearable sensors, which requires comprehensive characterization and testing.
Furthermore, this study explores the development of barium titanate scaffolds for the purpose of bone tissue engineering through the utilisation of additive manufacturing techniques. The scaffolds are being evaluated for their living organism compatibility, mechanical properties, and suitability for bone regeneration. This aspect shows the potential of piezoelectric materials to move beyond their conventional use in electronics and find value in other biomedical applications, thereby underscoring their versatility.
Finally, the thesis examines the utilisation of additively manufactured polymer-based barium calcium zirconate titanate composites in antibacterial environments, demonstrating its effectiveness against Escherichia coli. This approach highlights the adaptable characteristics of these materials and addresses the current acute issue of antimicrobial resistance in healthcare systems.
