dc.description.abstractTransient electronics are electronic devices with the ability to disintegrate/dissolve in a programmable manner, usually over a short period of time. Their by-products, after any dissolution, are usually harmless and benign, and hence they are an attractive approach to the global e-waste problem, especially for low-cost, one-time-use devices such as RFID tag antennas. This thesis focuses on designing and fabricating transient circuits with descent mechanical and electrical properties. To aim this, a laser is used to carbonize thin films made of nature-derived Lignin and graphene oxide. SEM, XPS, and Raman spectroscopy are used to study morphology and chemical composition of the films. Having optimized the material composition and laser parameters using four-point probe measurement, an RFID tag is designed and fabricated as a proof-of-concept. In the end, the transient property of the circuit is tested by dissolving the tag in water.
