Abstract Non-sustainable substrates, such as PET and PI, are used for the additive fabrication of FHE due to their excellent thermal, dimensional stability, and mechanical strength. However, their environmental impact is high due to minimal degradation even after decades in landfills. There is a growing global push for sustainable solutions for printed electronics. Recent studies indicate that alternatives like bio-based PET, polylactic acid, and regenerated cellulose film, all derived from renewable resources, might not only match but, in some instances, surpass the performance of traditional PET. While these materials show promise in certain environments, comprehensive research on their adaptability across various conditions remains inadequate. With the escalating demand for roll-to-roll manufactured electronics in diverse areas, ranging from packaging to healthcare, it becomes crucial to thoroughly evaluate these renewable substrates efficiency, longevity, and versatility. This research addresses these concerns, focusing on assessing the performance of bio-based PET substrates in FHE applications and comparing the performance with traditional PET substrates. Research Objectives include - (a)To understand the significance of Flexible Hybrid Electronics in the context of sustainable and environmentally friendly electronics. (b)To determine the compatibility and performance of the biodegradable PET substrate during the screen-printing process, especially while printing with water-based inks. (c)To test the performance of printed circuits and calculate the error percentage between the actual and simulated performance.
