Abstract

This paper presents an efficient, low-complexity, low-cost hybrid power harvester for supplying agricultural battery-free sensor nodes. The design is a solar/electromagnetic (EM) energy harvester that uses energy from solar radiation and NFC (Near Field Communication) technology at the same time. The design consists of an NFC coil antenna, a full wave rectifier operating at 13.56 MHz, a solar cell and a capacitor for energy storage. The NFC coil antenna is connected to the rectifier circuit that provides the rectification of the incoming EM signals and the collection of dc energy coming from the solar cell. The harvester was connected to a commercial dc-dc converter and the open circuit voltage was increased from 80 mV to 4.6V, charging a1000 μ F capacitor. The harvester was fabricated on FR-4 substrate in order to reduce the overall cost of the future sensor node. The stored energy could supply a sensor in a wireless network, with average power consumption 60 μ W.
