Researchers Create Computer That Fits On a Pen Tip 110

Posted by samzenpus from the because-they-can dept.
CWmike writes "Researchers at the University of Michigan announced Wednesday that they have created the first prototype for a millimeter-scale computing system that can hold up to a week's worth of data when implanted in something as small as a human eye. The computer, called the Phoenix chip, is just over one cubic millimeter in size and was designed to monitor eye pressure in glaucoma patients. 'This is the first true millimeter-scale complete computing system,' said Dennis Sylvester, a professor at the school and one of the researchers on the project. Within the computer is an ultra low-power microprocessor, a pressure sensor, memory, a thin-film battery, a solar cell and a wireless radio with an antenna that can transmit data to an external reader device held near the eye."

    • I've heard from a lot of Lasik/Lasek/Whateverik patients that its not uncommon to get a fair bit past 20/20. I'm not sure if that has consequences when you need to look at something up close though, I know how horrible that feels when I'm wearing my glasses so I can only imagine how bad it must be to have your eyes do that to you... maybe it doesn't though.

        That's because your glasses have to cheat a little, which gets obvious when you look up close. Many people have better than 20/20 vision, some exceptional subjects down to 20/8 - meaning they can read from 20 feet what a normal person can read from 8 feet. They have no problem with close objects - not more than everyone else, anyway - they just see everything sharper. Just imagine it like turning the focus on binoculars, they just have another notch where they see even finer details the rest of us can't.

        • I have 20/10 vision, but it's the difference between the eyes that allows such a large depth of clear vision; one eye 'leads' for close objects, and the other for objects far. Unfortunately, the 'fatigue factor' for those with vision like that is twofold; my doctor told me that I would be wearing glasses at thirty-five.

        • From everything I've heard, that's not how it works. People with eyesight in that range have better range of focus, not necessarily better acuity of vision.

          My brother is a pilot, and has better than 20/20 vision. He's approaching the age where he'll need bifocals, and is not (yet) wearing glasses. I'm not sure what his acuity of vision is, but I would be unsurprised to find it is also high.

          My vision is poor. Without glasses, I can't read a book that's 18 inches (45 cm) away. On the other hand, with my

        Yeah... about 7 or 8 years ago I got Lasik; about 2 years ago I started needing reading glasses (I'm 43 now).

        I'm going to find out if I can correct that, too. I don't want implanted lenses, though.

        • You can't with lasik. The muscles in the eye allowing them to focus for reading just get tired as you get older. Lasik can only fix the lens.

          • Reading glasses are for presbyopia [wikipedia.org], a diminished ability to focus at near distances, mainly because the crystalline lens [wikipedia.org] (which is inside the eye) gets less elastic with age. Lasik [wikipedia.org] _can't_ fix this, but there are multi-focal and accomodating intra-ocular lenses [wikipedia.org] that can. Multi-focal lenses have multiple focal zones for different distances, similar to bifocal glasses. Accomodating lenses are designed to adjust their focal length to mimic natural accomodation [wikipedia.org]. Lasik doesn't fix the lens. It is non-invasive an

        • The problem is simply that you're getting older. Focusing close and far require different shapes for the eye, and as you get older your eyes and eye muscles get less plastic and less able to make those large adjustments. Basically, your choice is to focus far and use reading glasses, or focus close and need distance glasses. Use a secondary device to create your second focal point.

    • Researching that right now in my basement lab. It's been partially successful, though unfortunately 9/10 patients become lobotomized vegetables. But we're working on that.

      Let me know if you'd like to sign up for a trial.

    Researcher Create Computer That Fits On Pen Tip

    My team obviously went the wrong direction. We've just completed work on a breakthrough - a pen that's large enough to fit onto a computer - comfortably. We figured that computers were tired of just writing to disk, so we'd let them write on paper as well. The actual apparatus is so comically large, that, obviously, only a large-ish computer would want to use it.

    Embarassing.

    • Interestingly, this exists, it's called a plotter. Quite useful in many situations, too, since you can replace the pen with, say, a waterjet or laser cutter, or an engraver. It's a 2D CNC machine.

These networks could one day track pollution, monitor structural integrity, perform surveillance, or make virtually any object smart and trackable.
