Using RFID for fiber composites
Research News Jul 01, 2013
Antennas that are capable of transmitting
radio waves turn components into intelligent objects. Researchers have
now found a way to embed these antennas in fiber composites. As a
result, the technology also works with carbon and glass fibers.It is barely visible to the naked eye: the work pieces in the production hall look normal. But the first impression is deceiving. The airplane components are “intelligent” and can communicate with the skilled workers in their vicinity. Not only can they tell them what they are, they can also provide information on who has worked on them as well as on the next work step. A radio frequency identification chip (RFID) transmits the information. It measures just a few square millimeters and transmits details about the component quickly, efficiently, and consistently to a receiver via radio waves. Until now, only a handful of companies use the technology for documentation purposes in production processes. Most often, RFID is used for access control purposes, or to record time, for instance on employee smart cards.
