Plug-In Multi-source Energy Harvesting for Autonomous Wireless Sensor Networks

Wireless Sensor Networks (WSNs) have a great attention in recent years due to their powerful advantages such as low-powered sensing, wireless communications and especially, effortless deployment, which are definitely suitable for various monitoring applications. In order to support a long system-lifetime and expect the batteryless powered WSNs, renewable energies such as solar, wind or heat are integrating in each wireless node for eternity power supply. In this paper, an efficient multiple energy sources platform is proposed. The interest of our design is that it is flexible to extend to different energy sources by using the plug-in mechanism. Our system is validated in the field to illustrate a monitoring application using WSNs.
