Abstract
Radio Frequency (RF) Wireless Power Transfer (WPT) is a technology that allows devices to be powered wirelessly. This project aims to develop a functional Radio Frequency (RF) energy harvesting demonstration kit, and to assess the feasibility of building a RF energy harvesting kit. The objective of the kit is to harvest and convert RF energy from a transmitter into DC energy to power up a sensor device, or end device. The main focus is on configuring and evaluating the power management circuit and the end device in the kit. The performance of the kit was evaluated. Testing results showed that the demonstration kit was able to power up the end device when RF energy is transmitted to the receiving antenna in the demonstration kit. When the transmitter is placed 94.0 cm away from the receiving antenna, the demonstration kit can be powered up with a minimum power of 21.90 dBm delivered to the transmitter, and the end device can be powered on continuously with a minimum power of 23.30 dBm delivered to the transmitter.
This project was sponsored by Nanyang Technological University (NTU) as part of the Nanyang Research Programme.
