Researchers at the Georgia Institute of Technology have developed a way to harness the power of electromagnetic energy. The team, led by Manos Tentzeris, has created inkjet printable ultra-wideband antennas that can convert microwave energy into DC power. Yep, antennas that can be printed from home (given the right ink, of course)! The premise is fascinating, as ambient electromagnetic frequencies are constantly available in the air. Some of the proposed applications for this new technology include: detection sensors, temperature and humidity monitors, sensors that check the structural integrity of buildings, quality monitoring of food, and bio-monitoring devices that can detect medical issues.
