GE's Battery-Free Sensor is a Breakthrough in RFID Technology
Posted by Sean Fallon at 5:50 AM on October 16, 2008
GE's new battery-free sensor could be just the kick in the pants RFID needs to start living up to its potential. The platform uses a conventional RFID tag coated with a chemically or biologically sensitive film that draws power wirelessly from a handheld reading device. Naturally, eliminating on-board batteries means that manufacturers can make smaller sensors (as you can see in the image above) at a lower cost. So, with any luck, this technology will lead to new tracking and info-swapping applications across a wider range of industries. [Gizmag]
Some people are sick of waiting for the RFID implant controversy to play out, and at least one of those people is taking action. YouTube user Quethe has 
Here's a challenge to hackers everywhere if I've ever heard one--a company named Verayo claims to have created an RFID chip that's completely unclonable thanks to a type of electronic DNA technology called Physical Unclonable Functions (PUF). Unlike basic passive RFID chips, where data can be easily copied from one chip to another, Verayo's PUF-fy RFID chips use a series of challenge-and-response pairs to make counterfeiting nigh impossible (or so they say.)
A superteam of British scientists and researchers are working on a nanotechnology that, when applied to gun cartridges, act as microscopic tags that place themselves on and around everything they come in contact with, such as criminals. The bullet tags are part natural pollen, part nanoparticles that are extremely difficult to wash off and can also keep skin cells stuck to the gun cartridges. The technology is said to be heat-resistant, cost effective and could be in use within a year. [
