Researchers debut one-cubic-millimeter computer, want to stick it in your eye
This as-of-yet-unnamed mini computer was fashioned as an implantable eye pressure monitor for glaucoma patients, but its creators envision a future where we're all crawling with the little buggers. Taking up just over one cubic millimeter of space, the thing stuffs a pressure sensor, memory, thin-film battery, solar cell, wireless radio, and low-power microprocessor all into one very small translucent container. The processor behind this little guy uses an "extreme" sleep mode to keep it napping at 15-minute intervals and sucking up 5.3 nanowatts while awake, and its battery runs off 10 hours of indoor light or one and a half hours of sun beams. Using the sensor to measure eye pressure and the radio to communicate with an external reader, the system will continuously track the progress of glaucoma, without those pesky contacts. Of course, the mad scientists behind it look forward to a day when the tiny device will do much more, with each of us toting hundreds of the computer implants all over our bodies -- looks like a bright future for cyborgdom.
