Printable Antenna Powers Electronics

Radio and television transmitters, cell phone networks and satellite communications systems transmit ambient in the air around us and researchers at the Georgia Tech School of Electrical and Computer Engineering have discovered how to scavenge and harness that energy to power small electronic devices. Inkjet printers are used to print these self-powered wireless sensors. Practical uses include chemical, biological, heat and stress sensing for defense and industry, radio-frequency identification (RFID) tagging for manufacturing and shipping, and monitoring tasks in many fields including communications and power usage.
