Description Wireless sensor network (WSN) deployments are rapidly increasing. Some research reported that in 2010, WSN chip shipments grew >300 percent and wireless-enabled building automation sensors grew 80 percent. The majority of these sensor nodes are battery-powered which deploy and install rapidly compared to wiring. The industry needs low-cost, reliable, and long-term power sources to scale WSNs and extend deployment into hard-to-service areas where wiring or replacing batteries is impractical or prohibitively expensive. As a result, there is tremendous interest in energy sources that can power sensors autonomously for the life of the application without wires or primary batteries. This is commonly referred to as micro-power energy harvesting where waste energy from ambient sources is converted into electrical energy. Student will study different energy sources and design a board able to store the producted energy in the most efficiently way. New technologies will be used in the future application that Envisens Technologies s.r.l., spinoff of the Polytechnic of Turin, will realize.
