Millimeter-Scale Computer
Greg Chen
Tiny-fingered researchers at the University of Michigan have created this computer, the world's first complete millimeter-scale computing system. It is a prototype designed to be implanted in a human eye, to monitor internal pressure there for signs of glaucoma.
The machine includes a teeny battery, a consolidated radio and antenna, a pressure sensor, memory, and a rather diminutive processor designed to consume extremely little power.

July 2013: The Future Of Flight
The incredible innovations, like drone swarms and perpetual flight, bringing aviation into the world of tomorrow. Plus: today's greatest sci-fi writers predict the future, the science behind the summer's biggest blockbusters, a Doctor Who-themed DIY 'bot, the organs you can do without, and much more.

Ow, my eye! I'm not supposed to get microprocessors in it!
Really, such an potentially amazing article and there isn't a single spec on the computer at all?
How much RAM? How much processing power? How big is it really? How long will the battery last before it needs to be replaced? I mean .. ANYTHING other than "hey look, it's tiny"
seriously. I could have written a better article, and I can guarantee I know less about it then them.
Not even a link to a source article so we can get real info on this thing? It must be Monday...
The size is two inches by three inches. That's just a really big penny.
But, can you play CoD on it?
Here's the link for more info:

Here's the abstract of the presentation on this system that was given at the International Solid-State Circuits Conference (ISSCC) earlier today:
A 1mm3 intraocular pressure monitor (IOPM) is presented for optimal implantation to track glaucoma and prevent blindness. It achieves 0.5mmHg resolution with a MEMS sensor and a ΔΣ capacitance-to-digital converter. The user wirelessly activates the IOPM, which responds by transmitting data using 4.7nJ/b. The 5.3nW IOPM harvests solar energy to recharge its battery at 80.6nW.

yeah. a little short on info. I am curious. It has a tiny battery. will it last for 50 years???
thank you isa3rjock for basically tripling all the info popsci offered and cleared up my battery question.
how are you supposed to type CTL+ALT+Delete when something crashes?
This is great medical news.
I wish the government would encourage and fund more research for all kinds of eye problems. And I think that is the expertise of Mr.Obama, to foster the habit of new innovations.
Soon we will see the similar devises to be implanted into the 21st finger, to implement a "hard on" tax.
