Antenna-free RFID tags in works at NDSU

A team of researchers at North Dakota State University uses microchips to enable pieces of paper to be tracked. Val Marinov calls it “smart paper.” Imagine pieces of paper that could broadcast their whereabouts. A team of researchers at NDSU’s Center for Nanoscale Science and Engineering has applied for a patent for a laser process they’ve developed to apply tiny silicon chips to paper. The process is not unlike a sophisticated version of screen printing techniques used for making T-shirts.
