Short-range Wirelessly Powered Sensor Network: Concept and Initial Measurement

Original language description

With rapid improvements in the reduction of power consumption of modern electronic in recent decades, a batteryless operation can also be achieved in small sensor networks. A common way to power such devices is by energy harvesting from sunlight, heat source, or vibrations. In applications, where none of them can be used, the alternative is to supply energy using wireless power transfer (WPT). Comparing a couple of WPT technologies, a radio frequency (RF) was chosen as a suitable candidate for powering a sensor network. In this paper, elements of the sensor network using RF energy powering in the lower frequency ISM (industrial, scientific and medical) band and wireless communication in higher frequency ISM band are proposed, and based on this concept, a sensor node with RF energy harvester is developed. For development purposes, a single-node network with RF power transmitter is built-up, and initial measurements are described. Results show that in the parallel configuration of transmitter and receiver antenna, the wave-character of RF radiation has a significant impact on the received signal strength, and proper positioning of the receiver relative to the transmitter must be ensured for sufficient energy harvesting in a real application. Another measurement proves this assertion and shows that misalignment to the peak of RF wave in closer distance from transmitter would lead to lower performance even in comparison to a node in the greater distance, but more precisely aligned.
