Design of a battery-free wireless sensor node


In this paper, a battery-free wireless sensor designed to harvest energy from electromagnetic waves at 866.6MHz and its detachable antenna system are described, with an emphasis on high frequency front-end design. In addition to having no local power source, the proposed sensor node is programmable, since it integrates a general-purpose microcontroller… (More)
