In this paper, we present the first ever wireless ldquoBattery-less Solar Powered Wireless Tagrdquo that can also communicate with wireless sensor networks for the first time reported. This RFID is based on the hardware/software codesign of five different technologies, and could set the foundation of ubiquitous ultra-low-cost RFID networks and the first generation of ldquogreenrdquo RF electronics...
A novel miniaturized 3-D cubic antenna for use in a wireless sensor network (WSN) and RFIDs for environmental sensing is introduced. The antenna produces a truly omnidirectional pattern in both E-plane and H-plane, which allows for non-intermittent communication that is orientation independent. The frequency of operation lies in the UHF RFID band, 902 MHz-928 MHz (centered at 915 MHz). The ultra-compact...
In this paper, the feasibility of inkjet printing process for the development of a ldquoSystem-on-Paperrdquo RF system was demonstrated for the first time. The process of designing a wireless transmitting sensor module entirely on paper was outlined and its performance was measured. The measured sensor results show good agreement with the manufacturerpsilas specs. The relatively higher heat insulation...
