NFC For A Penny

Transmitters costing a penny which can operate in the NFC 13.56 MHz frequency have been described in the Institute of Physics’ Nanotechnology journal by a team of Korean researchers.

‘Sensor networks such as RFID tags, price tags, smart logos, signage and sensors could be fully interconnected and utilised by DC power of less than 0.3W,’ says the paper.

The transmitters, in the form of a rectenna made up of an antenna, a diode and a capacitor, are formed using electronic ink on plastic foil using a roll-to-roll printing process.

The digital information to be transmitted can be printed into the rectenna.
