Hitachi Develops RFID powder

Posted February 14, 2007 7:37 AM

From Pink Tentacle:

Hitachi's new RFID chips (pictured on right, next to a human hair) are 64 times smaller than their mu-chips (left) RFID keeps getting smaller.

Excerpt: "But since existing tags are already small enough to embed in paper, it leads one to wonder what new applications the developers have in mind."

Fascinating. How are they connected ( soldered ) to a circuit and what type of power supply they use?

They're not, and none, respectively. These chips (and their other RFID cousins) are stand-alone, self-contained devices. While some older (and far larger) RFID devices contain some form of power pack, these devices are powered by the interrogator's RF field - much as were early crystal radios. Furthermore, they're transponders: they speak only when spoken to.

Care for some snuff?
