A Low Power Design for Radio Frequency Energy Harvesting Applications

Proceedings of the 2014 2nd International Symposium on Wireless Systems within the Conferences on Intelligent Data Acquisition and Advanced Computing Systems (IDAACS; 11-12 September, 2014; Offenburg, Germany)

Abstract anzeigen

A new design for a radio frequency (RF) energy harvesting circuit, which enables capturing energy from an electromagnetic far field, is presented in this paper. First, we present the state of the art of common energy harvesting systems. Second, we introduce some important preconsiderations concerning near and far field propagation and how to calculate the expected power at the input of the system. Third, we describe the design of a RF energy harvesting system. The system consists of a quarter-wave monopole antenna, a matching circuit, an energy conversion module, an energy storage capacitor, a low-power comparator and a DC-to-DC converter. The RF energy harvester operates at a frequency band of 868 MHz and creates a pulsed output voltage of about 1.8 V at an input power of at least -6 dBm. The system can be used to power a wireless low-power sensor node. With this approach, a battery-less sensor network is made possible.

Abstract anzeigen

The contribution introduces a RF energy harvesting circuit which can be used to power a wireless and battery-less sensor system. The sensor can be powered wirelessly over a distance of about two meters. The basic principles of RF energy harvesting are explained, it is shown how the system can be designed and special considerations are discussed. The proposed RF energy harvesting system operates at a frequency of 866.6 MHz, so that far field propagation is present. The system consists of an antenna, a matching circuit, a RF-to-DC conversion circuit and a power management module, including a storage capacitor, a comparator and a DC-to-DC converter. The harvester produces a pulsed output voltage of 1.8 V at an input power of at least -6 dBm.
