Fabricating and Investigating Laser-induced Reduced Graphene Oxide RFID Tag

Transient electronics and their dissolution byproducts, are usually harmless and benign, and hence they are an attractive approach for the global e-waste problem especially for low-cost, one time use devices such as RFID tag antennas. For this research, a straightforward laser-induced method of environmentally friendly reduced Graphene Oxide films is proposed for fabricating transient RFID tags possessing sufficient electrical and mechanical properties for proper functioning. First, the effects of fabricating conditions, such as laser power, exposure time, and laser scanning speed, on the final architecture and electrical/mechanical properties will be investigated using scanning electron microscopy, Raman, and X-ray diffraction. Having optimized the conditions, several hypotheses regarding the reduction process will be tested. First, it is hypothesized that the wider the Graphene Oxide flakes are, the higher the conductivity of reduced part will be. Furthermore, it is proposed that adding nano-additives like Carbon Nanotubes to make hybrids with the precursor (GO) will improve interconnectivity and reduce inter-facial effects between GO’s flakes, resulting in lower resistivity. The final expected outcome of research is a facile method of co-reduction of GO-based hybrids for biodegradable transient RFID tags.
