RFID Tags  

Radio frequency identification (RFID) tags are small devices that use radio waves to identify, track and communicate with people and objects. They are used in many industries including agriculture, manufacturing and healthcare. Active RFID tags have an integrated power source, usually a battery, that allows signal transmission over long distances. Nanoscale Energy Harvesting is small enough to be integrated into Active RFID tags, allowing device makers to explore new form factors and performance specs.
