Abstract
This thesis investigates the mechanical behaviour of stretchable conductive polymers, with a specific focus on Silver-Polydimethylsiloxane (Ag-PDMS) as the conductive ink and Polydimethylsiloxane (PDMS) as the base material. These materials are essential components in the development of flexible and wearable electronic devices, offering promising applications in fields such as health monitoring, robotics, and consumer electronics.
The primary aim of this research is to explore the performance of Ag-PDMS and PDMS under various mechanical conditions, specifically uniaxial and cyclic loading. The study employs finite element analysis (FEA) using Ansys Workbench software to simulate and evaluate the behaviour of these materials. Different dimensions and geometries of the conductive ink are analysed to understand their impact on mechanical properties, including total deformation, von Mises stress, equivalent elastic strain, and plastic strain. This research contributes to the advancement of stretchable electronics by providing critical insights into optimizing the design and performance of conductive polymers. The findings highlight the importance of material selection and design parameters in enhancing the durability, reliability, and efficiency of flexible electronic devices. By examining the mechanical responses of Ag-PDMS and PDMS, this study offers valuable data that can guide future innovations in printed electronics. Ultimately, this research offers recommendations for future work, emphasizing the need for continued exploration of stretchable conductive polymers to achieve improved performance and broader application in emerging technologies. The insights gained from this study are expected to significantly impact the design strategies for next-generation wearable and flexible electronics.
