"Researchers at the University of Michigan announced Wednesday that they have created the first prototype for a millimeter-scale computing system<http://www.computerworld.com/s/article/9210962/Researchers_create_computer_that_fits_on_a_pen_tip> 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<http://ns.umich.edu/htdocs/releases/story.php?id=8278>, 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."
