5-micron RFID? Yup.
Feb 14, 2007 23:01
Some of you may be familiar with RFID -- Radio
Frequency IDentification -- chips. They're
passive devices that, when excited by radio
waves, can respond with their own radio signal,
powered by the radio waves that requested the
response. They're also capable of storing small
amounts of data.
I actually have 4 such devices implanted in my body for experimentation purposes. Those, however, are the size of a small gelatin capsule (but made of glass), containing the chip and a tiny antenna.
Hitachi has stepped up the game several orders of magnitude, by reducing RFID chips by several orders of magnitude. Their new chip are so small they refer to them as "powder".
They're 0.05mm x 0.05mm, smaller than the width of a human hair. Each can store and transmit 128 bits of information.
This is small enough to embed in anything, including your money, your printer ink, your food...pretty much anything.
