Abstract
In this paper, the design of a novel flexible RF energy harvester utilizing hybrid printed electronics technology is presented for the first time. The proposed RF energy harvester operates at UHF RFID band (868 MHz similar to 915 MHz) for far-field RF energy harvesting applications. A concept of hybrid printed electronics which takes advantage of both flexibility of low-cost printed electronics and high performances of ICs is introduced. The passive components of the RF energy harvester, such as the circuit layout and the antenna, are printed on a flexible low-cost polymer substrate utilizing a catalyst-based inkjet printing process for the fabrication of copper metallization layers. The surface-mount devices (SMDs) are soldered on the printed circuit board. The proposed approach demonstrates the feasibility of implementing low-cost flexible printed electronics for the Internet of Things (IoT) and stand-alone ("zero-power") wireless sensor platforms.
