Tiny Chips That Know Your Name
The research of embedding microchips isnt entirely new.Back in 1988,Brian Warwick,a professor of cybernetics at Reading University in London,implanted a chip into his arm as an experiment to see if Warwicks computer could wirelessly track his whereabouts with the universitys building.
But Applied Digital Solutions,Inc,in Palm Beach,Fla. is one of the latest to try and push the experments beyond the realm of academic research and into the handsand bodiesof ordinary humans.
The company says it has recently applied to the Food and Drug Administration for permission to begin testing its VeriChip device in humans.About the size of a grain of rice,the microchip can be encoded with bits of information and implanted in humans under a layer of skin.When scanned by a nearby reader,the embedded chip yields the datasay an ID number that links to a computer database file containing more detailed information.
Chipping Blocks
Most embedded chips designs are so-called passive chip which yield information only when scanned by a nearby reader.But active chipssuch as the proposed Digital Angel of the futurewill need to beam out information all the time.And that means designers will have to develop some sort of power source that can provide a continuous source of energy ,yet be small enough to be embedded with the chips.
Another additional barrier,developing tiny GPS receiver chips that cuold be embedded yet still be sensitive enough to receive signals from thousnads of miles out in space.In addition to technical hurdles,many suspect that all sorts of legal and privacy issues would have to be cleared as well.
