RF-powered battery-less Wireless Sensor Network

Abstract

Wireless Sensor Networks (WSNs) have attracted more attentions due to its low cost and convenience. Despite the great potential, power supply restricts the application of WSNs. Especially in the environment such as rural areas, underground and underwater structures, the electrical wire or battery increases the cost of installation and brings the unexpected inconvenience. In this abstract, a far-field radio frequency (RF) powered wireless sensor network is presented. Moreover, a mesh network approach is proposed to solve the data collision issue caused by the discontinuous power supply. Test results verify the feasibility and reliability of this WSNs.
