Abstract

The widespread use of sensors in healthcare, manufacturing, and other control systems has attributed to the path toward a modern, safe, and interconnected society. Among the various sectors where sensors are gaining prominence, machine learning, artificial intelligence, and robotics are the most rapidly expanding ones. To date, however, issues including high production costs, inflexible and expensive materials, and insufficient sensitivity have limited their use in fields like wearable electronics, biosensors, and soft robotics. Inks enable designers to make cutting-edge goods in a wide variety of industries and fields, from 5G communications and automobiles to advanced packaging and healthcare devices. Biomaterials and green chemistry manufacturing have opened up a world of eco-friendly, printable, elastic, stretchy, and biodegradable possibilities. In addition, sensors are undergoing a significant transformation toward materials that can be recovered and reused, lowering the amount of e-waste. This thesis aims to create novel conductive inks from bio-based materials that could be applied in the flexible electronics field. The best features of the inks presented are their excellent electrical conductivity, adaptation to various printing method designs, good shelf life stability, noticeable adhesion to a broad range of substrates, and excellent durability, aiming to improve sustainability and reduce costs and fabrication complexity as well as enhance mechanical, electrical, and thermal properties.
