I Know That Many Dogs,

and some cats,

are micro chipped, and now this incredibly small micro chip can be used on us, image Columbia University, the implant developed by the Columbia University Engineers breaks new ground as the world's smallest single-chip system, which is a completely functional electronic circuit with a total volume of less than 0.1 mm3, that makes it as small as a dust mite, and only visible under a microscope. The tiny chip required some outside-the-box thinking to make, particularly when it comes to the way it communicates and is powered, the needle in the photograph is the business end of a hypodermic needle, the scientists imagine these types of chips being implanted into the human body, and then wirelessly communicating information on what they measure via ultrasound. In its current form this is limited to body temperature, but other possibilities include blood pressure, glucose levels and respiratory function.

"We wanted to see how far we could push the limits on how small a functioning chip we could make," says the study's leader Ken Shepard. "This is a new idea of 'chip as system' – this is a chip that alone, with nothing else, is a complete functioning electronic system. This should be revolutionary for developing wireless, miniaturized implantable medical devices that can sense different things, be used in clinical applications, and eventually approved for human use." amazing.
