A flexible RF energy harvester using a novel hybrid printing technology on low-cost polymer substrates is introduced in this paper. The presented printing technology is a hybrid approach taking advantage of the low-cost flexible printing and of the high-performance surface mounting technology. The design guidelines for the hybrid printed electronics, PdCl2 catalyst ink for inkjet-printing, and material characterization method using a ring resonator are discussed in detail. A flexible RF energy harvester is designed and its performance is experimentally verified for proof-of-concept purposes. The fabricated prototype generates more than 2.9 V when it is exposed to a power density around 1 μW cm-2 at UHF radio frequency identification frequency range, demonstrating the feasibility and capability of the presented technology towards scalable conformal autonomous low-cost electronics.
